How to Assemble a Jigsaw Puzzle

I have gotten some emails asking me to share tips for assembling puzzles and/or my method.

If you’re new to puzzling, returning to it after a long time, or just want to see how someone else does it, check out this walk-through.  In the end, no method is right or wrong as long as you get from Point A (bag of puzzle pieces) to Point B (completed puzzle). However, this is my standard operating procedure. If you have other tips/methods, please feel free to post them in the comments.

Note: The puzzle I’m working in this example is Bits and Pieces “Sidewalk Flower Sale” by Americana artist Susan Brabeau.

1.      Choose a spot to assemble your puzzle

 You need a place that is not going to be disturbed until you finish the puzzle (or one that can be moved), has decent lighting, and, most importantly, is large enough. All puzzles list their finished dimensions on the box, so you can measure if in doubt.

I recommend using a Jigboard.

I’ve been using a Jigboard for several years now and I never do a puzzle without it. A Jigboard is a large but lightweight board with a felted surface and a sheet of material that fits over the top. You can get them in various sizes, but I use my Jigboard 2000 for everything, even 1000 piece puzzles. I like having the extra space. You can get one here.


Why use a Jigboard? Because:

      • You can put on the top cover when you’re not working on it. This protects you from losing pieces to cats, dogs, kids, accidental bumps, earthquakes, food spills, etc. I always put on my Jigboard cover when I stop working on a puzzle.
      • You can move it off the table. If you have company come visit or need the table for a meal or whatever, just put the cover on the Jigboard, pick it up (careful to keep it flat), and slide it under a bed or the couch or wherever it will fit. Everything stays safe and dust free.
      • You can rotate the puzzle. I often rotate my Jigboard so that I can work on various sides of the puzzle more easily.
      • It makes the puzzle easier to flip the puzzle in the end. I have gotten in the habit of doing a temporary mount of my puzzles. In order to do this, I need to turn the puzzle over. That would be very difficult if the puzzle was just on the table.
      • It has a felt surface and slight edges which help keep pieces from falling to the floor.

Using a table instead

If you’re just getting started with puzzling, or don’t do very many, you may not want to invest in a Jigboard. It’s perfectly fine to use a table too. Just make sure the final dimensions of your puzzle will fit on the table. If you have kids or animals, you may want to put a large flattened cardboard box or something similar on top of the puzzle when you’re not working on it.

2.      Sort and turn up your pieces  

I arrange everything on my Jigboard, laying out the boxes I use for piece storage and dumping the bag of puzzle pieces in the middle.  Sorting is an organizing task that takes an hour or so at the start of your puzzle. I use a Jigsafe for piece sorting, which you can get here. There are other similar products on the market, just make sure they hold at least 1000 pieces, stack, and have inserts in the bottom (you’ll see why later).


This may seem like a tedious task (well, it is), but it will save you a lot of time in the end.  I watch TV or listen to a book on tape while I do it. I used to just dump all the pieces in the box bottom and pick through them constantly to look for pieces for whatever area I was working on. You can certainly do that. But sorting has beaucoup advantages:

    • It saves times. This is a “turn up once and done” approach. So instead of riffling through a big box of pieces over and over again looking for bits of red or whatever, you simply make sure every piece is turned face-up at the start. Then all you have to do is scan all the turned up pieces to find what you’re looking for.
    • It makes putting the puzzle together more enjoyable. There’s less of that ‘I can’t find that one piece with the white tip’. Because all pieces are turned up, you can easily find the piece you need and there’s no more ‘riffling’ in a box as you go.
    • No lost pieces. You can put the pieces away at night. Similar to the way I cover my Jigboard, every night when I’m done puzzling, I stack my Jigsafe and put the lid on. The pieces are now safe from pets, kids, or what have you. It’s a terrible thing to lose a piece, so this is really worth it.
    • You can slide the pieces right onto the puzzle when you’re ready for them.  Be sure to get a piece storage device that has inserts that can be removed so you can slide pieces, face up, onto your work surface. The cheaper storage solutions don’t have this, so be sure you look at a product carefully before you buy. If there is no insert in the bottom of the boxes, you have to pick up each piece by hand to transfer it to your work surface.


As you move puzzle pieces from the big pile into the sorting boxes, pull out the border pieces as a first priority. If your puzzle is rectangular or round, you should be able to identify the border pieces because they have a straight (or curved) edge. I always put all the border pieces in the smallest (lavender) box, even if I have to layer them a little.  If your puzzle doesn’t have obvious border pieces, because it has an irregular edge (like a shaped puzzle) just skip this part.

For all the other, non-border pieces, the main thing is to get them all face up and laid in the boxes.  But while you’re at it, you might as well do some high-level sorting. For example, in this puzzle there was a pink-orange building that was very distinctive, various blue clothing items, and lots of greenery with flowers. I put pieces that were clearly in one of those areas in separate boxes. Other than a few obvious color areas like these, I don’t spend a lot of time obsessing over what box to put a puzzle piece while sorting. That can come when I’m working the puzzle. The main thing is just to get the pieces all face up.

If you have more pieces than you have storage boxes, you can put any extra in a separate container (like I did here – this was a 1500 piece puzzle and the Jigsafe holds 1000 pieces). I tried to toss in the extra container pieces that were dark or green or otherwise didn’t jump out at me immediately as going in a particular area. As the Jigsafe boxes are emptied when I work the puzzle, I will fill in the space with pieces from the extra container.

If you don’t want to invest in a JigSafe or similar storage product, you can try using shirt boxes or long flat tuperware containers. Alternatively, you can just use the ‘dump them all in the puzzle box bottom’ strategy and look for pieces as you need them.

3.      Assemble the puzzle border

If your puzzle has an irregular border (like a shaped puzzle) or has a very difficult border (for example, all one solid color), then you should skip this step and put the border on as you go or even at the end.

The main advantage of assembling the border first is that it gives you a framework within which you can lay out the rest of the puzzle. It forms the XY axis of your grid. And it also gives you lots of edges to attach to along the sides.

At this point, I have all my border pieces isolated in the smallest storage box.  I put the other boxes away and slide the border pieces onto my work surface.


This is where it’s really handy to have storage boxes with an insert in the bottom because you can just lift the insert out and slide the pieces onto your work surface face-up, like in the photo above.


When assembling the border, I generally just put together pieces based on color and pattern for as long as it’s easy. So I end up with something like the photo above.

At this point, I look at the puzzle image and start moving around the sections to where they actually should go. Then I can connect the sections and add in pieces to fill out the rest until the border is complete.


4.      Assemble the 3-4 easiest  areas of color/pattern first

Many puzzles are a combination of relatively easy, obvious areas and areas which are more mixed, dark, monotone, or vague (like a huge area of blue sky).  Let’s take a look at the image in this sample puzzle.


Looking at this image, I would say the easiest areas are: the large pink brick building, the bricks on the ground in the lower right, the blue clothing, the red-and-white awning in the upper left, the yellow flower clusters, the faces, and the white-ish buildings with blue windows in the background. When I did my sorting, I already isolated the pink building pieces and blue clothing.  Notice that I didn’t chose the greenery as an ‘easy’ area. That’s because there’s quite a lot of greenery spread out all over the image, and greenery tends to be a random pattern that isn’t as easy to assemble. So I’ll wait to do those spots.



5.      Once several areas are assembled, take a moment to arrange them in place in the frame

Working a jigsaw involves not only color/pattern recognition but also spatial relationships. Usually after I have several ‘easy areas’ or vignettes, I spend a few minutes arranging those areas within the frame of the border, placing them as close to their final place as I can just with eyeballing. If your puzzle has a border, you can use it as reference, lining up with two sides like an XY table.

Below is my example puzzle so far with the the areas I thought were the ‘easiest’ now assembled:


Some areas attach to the puzzle border, so they are already locked in the right place. But some, like the faces in the middle, are floating at this point. Let’s put them in the right place.


Above: in the image, we can see the man’s face in the middle of the composition lines up with a pinkish pot on the “X Axis” border.  On the “Y axis” border, he lines up with the tree trunk. Using the puzzle border I completed, I can place the man’s face roughly in the same spot on0 my work surface.


By placing finished areas in their correct spatial location, you might see that they actually link to a nearby section (the man’s face is close to linking with the white/light pink buildings). Or, as you find additional pieces, you can easily tag them onto a completed section and won’t have to worry about moving it later on.

All the areas you’ve assembled so far can be fit into the frame with this technique before you move on.

TIP: Don’t waste time ‘trying’ pieces that visually don’t fit. This may seem obvious, but when I sit down with new puzzlers, I see them pick up one piece and try it in many places all over, even in places where it obviously could not go. It’s as if they hope it will just ‘work out’ . This is spinning your wheels. LOOK at the piece and the edges first. When you attempt to attach a piece to an edge, you should be at least 80% sure it will fit. Do the colors and patterns on the edges you are attempting to connect match? Is the knob and hole that will connect roughly the same size and shape? I do so many puzzles that now I rarely try to attach a piece where it doesn’t go. I’m actually surprised when a piece I attempt to put in place does’t work!

6.      Repeat Steps 4 & 5 through all the ‘obvious’ or ‘easy’ sections of the puzzle

As long as you have clearly defined areas within the composition, you can continue to a) isolate those pieces, b) assemble (if you run out of clear area on your workspace, you can assemble in one of the Jigsafe boxes), and c) put them into the correct spatial location in the puzzle.

Why work the easiest areas of the puzzle first? It’s more efficient and will save time for the following reasons.

  • You are removing pieces from the playing field. When trying to find the pieces for a given area, your eye has to roam over all available unassembled pieces. As you move groups of attached pieces onto your board, you are removing those pieces from play, as it were. And that saves time when scanning for pieces for the next area to assemble. Choosing the brightest, easiest pieces to spot first just means when you get to the harder sections, you have less scan work to do.
  • You are providing more and more ‘edges’ to attach to. As you scan the boxes for the next area’s pieces, such as ‘the greenery’, your eye will notice pieces that go with areas you already assembled since they are fresh in your mind. Oh, look, there’s a blue tip, that must go with the dress I just did. This is true, even if it’s not the piece you’re currently looking for. You can pluck that piece up and put it where it goes. The more ‘edges’ you have going on on the work board, the quicker the assembly will go.  So create the most edges as fast as possible by doing the easiest areas first. 

In the image below, I’ve assembled all the areas in the puzzle that have easy to recognize color and pattern. What remains are the greenery areas and the darker or vague areas.


7.      Assemble harder color/pattern areas

Now that I’ve done the easiest areas I can tackle other areas that are a bit more difficult, large,  monotone, or spread out. For example, a large area of plain blue sky might fall in this category (though not in this sample puzzle). So I’m going to do the greenery next. It’s a little harder because a) there’s quite a bit of it and it’s spread out in different areas of the puzzle and b) greenery (leaves, trees, plants) are a randomized pattern, not a regular pattern like bricks or clothing.

At this point, I have a lot less pieces to deal with and all the green pieces are in 3 boxes.


Even though this is all “greenery” (plants), it’s not all one color. There are darker greens, lighter greens, fuzzy greens (the trees) and detailed leaves (plants in the foreground) and bits of small flowers throughout. So I can work similar colors and textures into larger and larger groups and put them where they go in the puzzle.


Above: The greenery is complete. Now I only have darker and indistinct areas of the puzzle remaining.

TIP: If you try to fit a piece, and can’t figure out where it goes, don’t waste time on it. Chances are good it’s an ‘inside’ piece you don’t have edges for yet. Put it to one side in a hold area. Later on there will be a lot fewer places it CAN go (and new edges), so there’s no point in grinding gears on it now. Do set it aside though–I find myself picking up the same piece over and over if I don’t put it up in the corner of the Jigboard or some other ‘leave it alone’ designated area.

8.      Finish up the dark or vague areas

There comes a point in every puzzle where there’s maybe 5-10% of the puzzle left and the pieces just aren’t obvious. They don’t have that ‘blue tip’ or whatever to scream out their location. They might be dark, monotone, indistinct, transition pieces, etc. Below is my box of these last pieces for this particular puzzle. I tend to consolidate my boxes as they empty out by sliding the remaining pieces in one box into the empty space in another (again, the bottom inserts come in handy!).  Note that the remaining pieces aren’t all black in this case, it’s just not immediately obvious where they go.


I now have lots of surface complete on my puzzle, so I prefer to slide the remaining pieces out of the box and onto the finished areas of the puzzle so they are close to the edges and I can see more easily where they might go.

If you really look at each piece, you will probably find that very few are completely without a hint. One might have a thread of green leaf or a tiny tip of a red hat or something else that tells you where it goes. If all else fails, you can compare the piece to the box image. And if THAT fails (such as an area of black) you can just try pieces until one fits.

TIP: When working random pattern areas or monotone areas, you’ll need to pay more attention to the shape of the piece rather than color. In the same way we did the ‘easy areas of color’ first, now look for ‘easy shapes’ — empty edge spots that have an uncommon shape, like a really fat hole that will require an extra large knob, or 3 holes that will need a 3 knob piece. These will be easier to find among your loose pieces. Filling in the easy shapes first once again takes pieces off the playing field and adds new edges.


TIP: As you do more puzzles, you’ll get faster. Your brain will get better at recognizing subtle differences in colors and patterns, and in the precise shapes of knobs and holes. This is great exercise for your brain and can even stave off memory loss, dementia, and alzheimers in your older years.

Here’s the finished puzzle.

  1. Loved finding your blog! It’s been a great help in figuring out which puzzles to buy and which to avoid!
    I never really did puzzles. I had a couple as a kid, but I had no technique and it was frustrating to see my teenager sis come along and start putting everything together so quick. So, in my adulthood, I bought – on occasion – a 500 pieces puzzle, and then a set of 3 500 pieces puzzle which I started and gave up almost instantly.
    And then, last week, I was cleaning my house, got the boxes in my hands again, started one and it took me 2-3 days/evenings for one. I was hooked! I had two days off and did each of the remaining ones on each day and ordered a couple of 1000 piece puzzles with the help of this blog – trying brands other than Ravensburger, which is, understandably, the most popular brand here in Germany. 🙂
    I use the same technique as you, though for both the border and large flat areas I quickly developed a technique that I call “brute Force”: I organize the pieces in groups of 0, 1 and 2 (as in the number of tongues sticking out). This saves me time when I’m looking for pieces of a particular shape (as you described in your post). For the border, I use even more force: 0s, 1s and 2s arranged in groups, the 1s arranged by which side the tongue sticks out, and then I pick up a piece, look where it clicks, lay that piece down, pick the “new” piece up, see where it clicks, put that piece together with the one I put aside, pick the “newer” piece, etc etc. It’s very practical for borders that are all the same flat color (as was the case with the 3×500 pieces I assembled). 🙂

  2. I must be an anarchist at heart… I don’t sort the pieces, I don’t do the border first LOL If I’m doing a 1000 pieces or under I just throw all the pieces on the table and work on assembling the pieces, without any method LOL For bigger ones, I just leave them in the boxes and try to find pieces that go together. I often end up with a lot of small assembly of 2 or more pieces and then find out how they go together, based on color and texture

    Oh, and I don’t use the cover or image… I prefer to “discover” the image when it’s done.

    Yes, I might be a little crazy, but that’s how I like to do it, and I’m lucky, my husband and kids accept me as I am, and assemble puzzles the same way 🙂

  3. Love the site. The company comparisons are spot on with my experience. I am a long time puzzle maker and prefer comic cartoon puzzles from 3000 to 5000 pieces. My three favorite brands are Jumbo and Ravensburger, tied for first place, and Heye (triangle box) comes in 3rd place,as I cannot pick up a grouping of pieces together. All three brands have artist I enjoy, but my favorite is JVH and I have all his puzzles 2000+ pieces except for Ice Hockey. I have my eye out for it on Ebay and Amazon, and of course the JVH site. I will work on any fun puzzle as long as the colors are bright, as I dont care for dark areas. I do not work on puzzles with lots of background sky or water.

    I am currently working on the Ravensburger Mickey through the years 40,320 piece puzzle. For those of you not aware the puzzle has 10 separately packaged scenes and most people will never put them all together at one time. It is just a great way to purchase 10 puzzles that are approx 4000 pieces each. There is definitely limited inventory of quality cartoon puzzles in this range.

    Anyways, I am never in a rush to complete a puzzle, and to be honest I have to add a challenge to puzzle making to slow myself down. I work on puzzles from top to Bottom. This requires me to work on whatever images are at the top of the puzzle, but allows me to work on the top of the puzzle with it right in front of me, without reaching or leaning or walking around the table. I get to enjoy each area of the puzzle and when 95% finished with the top 1/4 or 1/3, I move it up higher and start working on the middle section.

    I wanted to provide you with some feedback as my appreciation for your sharing your opinions on the site. I also recently noticed that the JVH site will help to replace missing puzzle pieces for a nominal shipping fee, as long as you provide very specific detail about where the missing piece is located in the grid. Dont just take a picture of the missing piece as they require both a pic and grid count. I bought a used 5000 piece puzzle circa 1995 from this site a few years ago and they shipped it with a replacement piece in separate bag connected with the 8 surrounding pieces, as they knew one piece was missing. I received a very nice note explaining about the piece (not the exact match but close) and it made me feel wonderful as there is nothing worse then making a puzzle and finding out you have missing pieces.

    thank you again,
