What shapes and sizes do the blank puzzles come in?

Material and build quality

The puzzles are constructed from sturdy cardboard that holds together well during printing and handling. Each puzzle comes pre-assembled in a single sheet, so you can apply your design without having to piece it together first. The surface is smooth and shiny, which helps sublimation inks adhere clearly. After transferring your image, you can break the puzzle apart into its individual pieces.

How to personalize and print on the puzzles

These blanks are designed for sublimation printing, but you can also use paint, markers, dyes, or even graffiti to decorate them. For heat transfer, the recommended settings are 360°F for 45 seconds. Simply print your design on sublimation paper, place it face down on the puzzle, apply heat, and then peel away the paper. The result is a vivid, permanent image that won't peel or fade easily. Using these puzzles can also encourage creativity and hand-eye coordination. They make a fun group activity where friends or family each decorate a puzzle for a group collage. Because the surface is blank, you have complete freedom to design anything from monograms to full-color photographs.

Who can use these puzzle sets?

This product is great for crafters, teachers, parents, and anyone who enjoys DIY projects. You can create custom puzzles for party favors, holiday gifts, classroom activities, or personal keepsakes. The two shapes offer variety: rectangular puzzles for standard designs and heart-shaped ones for romantic or Valentine's Day gifts. They also make thoughtful graduation presents or thank-you tokens when printed with a meaningful photo.
