What you need:
Printed out picture of your choosing
Print out any picture you like, but make sure it is at least as long as your popsicle sticks. Clip your picture a little larger than the sticks. Lay out popsicle sticks and line them up flat end to flat end.
Brush Mod Podge over all the sticks. Carefully lay your picture over the sticks, then firmly press down, making sure it is completely stuck to the glue on the sticks. Brush Mod Podge over your picture.
Allow all the glue to completely dry. Once dry, using your exacto knife (adults only here!) cut each stick away from the others. Flip the stick over on the side without the paper. Cut the excess paper from around the corners.
There you have your very own custom puzzles! Cheap, easy and fun!
