I try not to have too much stash due to $$$$$. I buy all the fabric to make the quilt. There is usually some left over so that becomes stash. Check Hobby Lobby (in your area or on line) their fabric is pretty nice and is usually 30% off.
Also if you just feel like sewing and want to learn check to see if there is a church group in the area that makes quilts. They can always use extra hands and may have extra fabric. At least you can sew, learn, socialize and do good!
