Hey.. I was thinking about what I could make for my little cousin's birthday and I decided on a little puzzle they can do.
First you print off the picture and back it with thin cardboard or thick paper and cut around the whole thing and get the child to draw a picture on it. Then, cut along the lines and they have a puzzle

Right now its 3x3 but I can make bigger if anyone is really interested
