I found this fun idea on Lu Bird Baby and thought it was perfect for a little Valentine's Day gift for those kids in Montana that I miss so much! The little mailboxes are from Target's dollar section right (found them the beginning of January) and the rest is from Hobby Lobby - felt and velcro. I sewed little envelopes and put velcro for a closure. The envelope also has velcro on the front to change the stamp and "mailing label". There are letters to put in there, but it will be fun for the kids to write their own notes too!
