A piece for each maker
The PDF includes a color answer for you, an assembly map and a numbered sheet for every piece. No student logins needed.
ONE PICTURE. A WHOLE GROUP.
Small pieces.
Big reveal.
A secret picture, made together.
Give everyone a numbered coloring sheet. Put the pieces together and watch the mural appear.
Original demo: Rocket
Your shared color key
Everyone uses the same numbers. White means leave the paper blank. Choose the closest colors in your own supplies.
FROM A STACK OF PAPER TO A GROUP MASTERPIECE
Keep the answer to yourself.
Hand out the possibility.
Follow one shared key
Match each number to a color. A small palette makes it easier to share supplies and keep everyone's colors consistent.
Find where it all fits
Trim the square outlines, match the piece IDs to the map, then tape the backs together. The whole picture is your group effort.
MAKE YOUR FIRST ONE WORK
A little preparation.
A much better reveal.
A few things worth knowing
Is this free, and do I need an account?
The maker and downloads are free. There are no accounts, subscriptions or paid image services.
Are my photos uploaded?
No. Image conversion and PDF creation happen in this browser. The hosting provider receives normal page requests, but the picture you choose is not sent to us.
Does this create smooth coloring-book outlines?
No. It makes a square pixel grid with a number in every cell. Simple illustrations work better than complex photos at small sizes.
Can I use a different number of participants?
Choose a supported piece count, then pair people or share extra pieces. Piece counts describe printable squares, not a promise that every participant gets exactly one.
Will my work still be here if I close the page?
The current picture and settings are not saved. Download your PDF before leaving. You can always recreate it from the original image.
Can I use the sample artwork in a class?
Yes. These simple sample designs were created for this tool and may be printed for personal, classroom and group activities. For uploaded images, use work you own or have permission to adapt.
