I've seen these 'letter crafts' all over Pinterest and I love them! We've been slowly working our ways through the ABC's (actually, we've only made it through A, B, and C, but D is coming today). This is what we have so far:
A is for Alligator.
B is for Butterfly.
C is for Caterpillar.
This one is made out of a sock and it's my favorite.
