Hi:
I just saw something on QNN that might be of help to you. The teacher had a quilt with a scalloped edge and what she did was cut a strip of fabric about 4 to 6 inches wide and put right sides together with edge of her scalloped quilt. She then sewed the scalloped edge 1/4 inch seam allowance all the way around then very carefully folded and pressed the strip back over the edge and sewed it down on the back side folding the raw edge under and sewed it down by hand or you could hand whip stitch it then when you quilt that part of your quilt, catch the edge of the strip that has been folded over. This application will stabilize the edge of your quilt and will give a nice finished look to the quilt without alot of time and work. You might want to check out QNN (QuiltersNewsNetwork) to see if they run that particular application again sometime. Sorry, I don't remember the teachers name or what they called that segment. Good luck!
