Cookie sheets painted pink! My daughter would love this. I've gotten large cookie sheets at the dollar store, and spray paint at Wallyworld. This is cuter and less expensive than a corkboard. Magnets can be glued on the back of anything light. My favorite magnets are made of small pieces of sea glass and quartz stones found at the beach. When I make thiis for my daughter, she'll probably add some of her favorite plastic mini-animals to the magnets.
