You've sorted your edge pieces, pieced together the colourful details and made great progress on your jigsaw puzzle. But now you're left staring at a sea of blue sky, an endless stretch of ocean or a seemingly impossible expanse of green grass.
Sound familiar?
Large areas of similar colour are one of the biggest challenges in jigsaw puzzling. With fewer visual clues to guide you, finding the right piece can feel like searching for a needle in a haystack. But don't give up! With a few clever strategies, you can turn those tricky sections into a satisfying part of the puzzling experience.
Here are our top tips for tackling those seemingly endless stretches of sky, water and other single-colour areas.
1. Start with the Subtle Colour Differences
At first glance, that big blue sky might look like one solid colour, but take a closer look.
You may notice subtle variations that can help you narrow down where pieces belong:
- Lighter blues near the horizon and deeper blues towards the top.
- Hints of pink, yellow or purple in the clouds.
- Darker patches, reflections or ripples in the water.
- Slight changes in texture or shading.
Our tip: Sort your pieces into smaller colour groups before you start. Even separating light blue from dark blue can make a huge difference.
Good natural lighting is particularly helpful here, as artificial light can sometimes make subtle colour differences harder to see.
2. Sort by Piece Shape
When colour isn't giving you enough clues, it's time to let the shapes do the talking.
Most traditional jigsaw puzzles contain a variety of piece shapes, depending on the brand and cutting style. Sorting these can dramatically reduce the number of pieces you need to examine.
Try grouping pieces by:
- Two tabs and two blanks (the classic puzzle piece).
- Three tabs and one blank.
- Three blanks and one tab.
- Two adjacent tabs or blanks.
- Unusual shapes or distinctive features.
Once you've sorted your pieces, examine the empty space you're trying to fill. If you need a piece with three tabs, you can immediately ignore all the others.
Our tip: Arrange pieces in neat rows, facing the same direction. This makes it much easier to scan for the shape you need without constantly picking pieces up and turning them around.
If your puzzle has a random or irregular cut, focus on distinctive outlines and unusual shapes instead.
3. Work from the Edges Inwards
Rather than randomly trying to connect pieces in the middle of a large area, work from sections you've already completed.
A finished border, a mountain range, the edge of a building or the horizon provides a solid starting point.
Look at the shape of the gaps along these completed sections and find pieces that match. Each new piece creates another clue for the next one.
You can also build small clusters of pieces separately and connect them to the main puzzle later.
Our tip: If you're tackling a large sky, complete the horizon first. It often provides the strongest colour and shape clues, making it easier to work upwards.
4. Look Closely at the Piece Cut
When the colours are almost identical, the tiny differences in the way pieces are cut become especially important.
Pay attention to the width of tabs, the depth of blanks and the angles of the piece edges. Some tabs are round, others are slightly flattened or offset to one side.
You might notice that a particular gap has a narrow tab opening or an unusually angled edge. These details can help you identify the correct piece even when the colour offers no clues.
Remember, a piece should fit naturally. If you need to force it, it's probably not the right one.
5. Use a Puzzle Sorting Tray
Sorting trays can be a lifesaver when tackling large sections of similar colours.
Instead of having hundreds of blue pieces scattered across your table, you can organise them into manageable groups.
Try dedicating separate trays to light blue, medium blue, dark blue and different piece shapes.
This keeps your workspace tidy and makes it easier to concentrate on one small group at a time.
Our tip: Don't have sorting trays? Shallow containers, baking trays or sheets of cardboard work just as well.
6. Change Your Perspective
Sometimes the simplest trick is to look at your puzzle differently.
Try rotating the puzzle board or approaching it from another side of the table. A piece shape that was difficult to recognise from one angle might suddenly become obvious from another.
You can also rotate individual pieces in your sorting area so they're all facing the same way as the gap you're trying to fill.
And don't underestimate the power of taking a break! Stepping away for a few minutes can help you return with fresh eyes.
7. Don't Be Afraid to Leave the Hardest Section Until Last
There's no rule that says you have to complete your puzzle in a particular order.
If that enormous stretch of sky is becoming frustrating, move on to another section. Work on the buildings, trees, animals or other distinctive details first.
As the rest of the puzzle comes together, the remaining gaps become smaller and easier to manage.
By the time you return to the sky, you might have far fewer pieces left to choose from.
Our tip: Save a particularly recognisable detail, such as a bird or a small cloud, to give yourself an easy starting point when you return.
8. Embrace the Challenge!
Large areas of similar colour can test even the most experienced puzzlers, but they can also be incredibly rewarding.
These sections encourage you to slow down, pay attention to small details and develop your piece-recognition skills.
If you're feeling stuck, set yourself a small goal. Rather than trying to finish the entire sky in one sitting, aim to place ten pieces or complete a small section.
Every piece is progress!
