God, I love your stuff. Especially that bag/hat combo. I LOVE that hat. I mean, I saw it and said "Jesus Christ, I need that hat." *coughs* Yes.
Not quilted, it's this cool piece of vintage brown paisley velveteen I found. The back is bonded with Pellon, then it's lined and topstitched. I used pellon on the bottom too. It holds it's shape better.
