I found this pack of magnet sheets (2 sheets for about $3) at Walmart-Mart.
Peel off the paper backing and lay the sheet with the sticky side up.
Peel and stick a set of fun stickers onto the sticky side of the magnet sheet. These ones are slightly puffy with a rough texture which makes them easier to move around. I found them at dollar tree.
Cut around each sticker carefully.
Be sure to cut all the extra off around the edges so only the sticker shows from the front.
Once you've cut out the magnets they will be ready to use!
Let your kiddos create scenes and tell stories using the magnets on a metal surface. I've seen pie pans and small baking sheets used for travel versions. This pic is of a small magnet board from Ikea.
