I've done it several times. But one time I didn't know it until it was too late. I had made one of Kaye Woods' starmaker triangle log cabin quilts about 20 years ago, got down to one strip about 2" by 8" and no more fabric. They still had it at the store and I could have gone and bought more but I thought "Grandma Mac would turn over in her grave if I went to the store to get more fabric", so I pieced that one little strip. It took 4 itty bitty scraps to peice a section big enough to make that strip. I was so proud of myself. The day I got the binding on I found 3 yards of the same fabric in a closet that had been bought at a different time. It was a good lesson in keeping all my fabric in the same room.
