My mom took my girls' old jeans to make a quilt. She used all parts of the jeans. The back pockets were included, and she put a little toy or book in each pocket. Mom also used the front section (with the zipper) She backed it with cotton fabric, and put a tie 'belt' in the loops. The zipper can be unzipped, and the pocket is used for a pajama pocket.
I'll see if I can get a pic and put it on here.
