OK Maybe not scraps only but because of the economy I, and the gals in my quilt bee, have been very motivated to use only stash fabrics. I do love the challenge but at times it is hard when you have specific requests from people for colors etc.
This might be a good idea for other people too. One thing that also works well for me is to share fabric. At this point it is more a of a what comes around goes around, no money or trading involved, but it seems to be working well. So maybe your scraps don't work on their own but put together with other people's scraps one person will be able to make something out of it. It is satisfying to see the fabric used in a beautiful project.
I also like the spirit of the originally quilters that used what was on hand. In a slightly different light several ladies in our bee buy used clothing at the resale and make quilts out of them. They moslty buy man's shirts and muumuus as they tend to be cotton and have larger pieces of fabric.
