Peggy Martin had a great tip that I love and am using for a quilt i am working on now.

All those little pieces that you can't throw away can be used. Get a roll of adding machine tape, the kind that does NOT have thermal treatment. Then just sew your little scraps on that! Make them wonky, make them uniform, no problem. Then use as a border around a block or your quilt. Voila!

It's like paperpiecing, just no pattern to follow. It's fast and fun and you use up your little scraps too.
