I, too, make magnetic bookmarks - usually out of card stock or like Luscious Marilyn does, recycled greeting cards - anything with a stiff paper/card stock. I just delivered over 500 of them to my daughter's elementary school as an incentive for their reading program for the younger kids. They have to read so many books to get prizes. I make mine about the size of a 3 x 5 card, folded in two, then put the sticky coated magnets on the inside and decorate the outside with stickers - geared towards the recipient's age or interest. I get the sheets of the sticky coated magnets at WalMart and cut my own about an inch long.
