I have the top to a denim quilt I made many years ago. The flannel backing long since fell apart. I took it off and have new flannel to put onto the back but the seams are falling apart in many places. I have patched it so many times and still can't seem to get in front of the frey. I have thought and thought about how to rescue this top. Then in looking at the pics here I see someone who has made a rag quilt from denim. It hit me then. Fold the seams to the front and reseam 1/2 to 3/4 inch in and make a rag quilt out of it. It will be a good bit smaller but it will not frey apart. I think I need to try this.
