I agree - never, never throw away your stash!
For those who have long pieces of fabric, you can pick up the actual bolts from various fabric and quilt stores. Just go in and ask for the empties, which are usually thrown away. I did that with our local Joann's and the gal was thrilled to give me 10 bolts to wrap my fabric around. I use them for the quilts I'm working on and they work fabulous!!!
