Guests wrapped letters in yarn for an Alphabet wall for the baby's nursery. What if not just yarn, but lots of other coordinating decorations, like beads, doilies, paint, etc? So not every letter is yarn and it's a little more personalized?
I have been looking at this idea for awhile...I love it! Have each person sign the back with a message too-take a picture as they walk in with their letter so you can make a alphabet book from Shutterfly starring family and friends!
