My three-year-old niece was really into playing Chutes and Ladders. The playing pieces that come with the game are made from a plastic base into which is placed small cardboard cutout with pictures on them. She kept referring to the pieces by her family member's names (her parents, little brother, and herself). I realized it would be a simple matter to create new pieces using photos of her family to replace the ones that came with the game.

Take photos of each person. It can be a lot of fun to create action poses for the camera. Or have the kids draw pictures of themselves. The images work fairly well as either full-body or from the waist up, but you probably want them all to be the same.

Insert the photos into a document. I used the word processor in the LibreOffice suite because a) it's free and b) it has enough tools to edit the photos without requiring separate image processing software. What you want to end up with is two copies of each photo cropped close around the person, a normal and reverse image for each character. If you're comfortable doing that you can skip to the assembly step.
