Sometimes just some mindless sewing will do the trick. Cut up some of your scraps into simple squares or strips and make a quilt to be donated to charity. I always have a quilt like this on the go and often stitch on this if I'm tired, between projects or lacking ambition. The Downey "pattern", a 8 1/2" focus fabric square alternated by a co-ordinating 4 patch is easy, quick and useful!
