We just made a bunch for a charity quilt night at my LQS. We cut scraps into 3" and 4" strips and sewed them together into 3" and 4" LONG strips (you could quickly get to the 36" length). Then we sewed the long strips together, alternating 4" and 3" strips to the length we wanted. There were 7 or 8 of us, and we got 7 tops completed in under 3 hours. The nice thing is that the seams are NOT supposed to match, giving it a cute randomness of design, and it makes a great scrap buster. Quilting can either be stitch in the ditch or a random meandering pattern.
