This project didn't take long at all. Maybe an hour or less. The key is to pre-quilt a 12 x 12" piece of fabric. Then cut it into the required size pieces. Next time I make this, besides using a coordinating zipper color :), I would not bother with the badge holder plastic in the front. It made it hard to turn inside out and I'm not using it for a conference so it's really not needed.
