My boys like anything with wheels. This year I bought some blank cards and lay them out flat over several sheets of freezer paper. Then I dumped some paint out and let the boys drive various small trains, trucks, and cars all over the cards. I cut out some trees and Ethan glued them to the front. Not bad looking, all things considered, it would have been nice to get them done in time to mail out, however... = ) Maybe next year!
