I must say that these ideas are extremely clever; I would certainly never have thought of them myself!  For Vistaprint’s Snow Day Five they have magnets specifically to be used as kids puzzles. Upload a favorite photo to make your own customized puzzle. Cut it up into fun shapes and have your little ones put it together on the fridge! You could also upload a page of words or letters to make your own magnetic poetry or spelling magnets.  That’s $4.99 for a small magnet (11.25″ x 8.5″) or $9.99 for a large one (17.3″ x 11.25″), which includes FREE shipping.
