repairing a quilt?
I am in possesion of a quilt top that my great grandmother made and I finally found a backing that works with the top. While awaiting the arrival of the backing and batting, I was looking at the top to figure out how to quilt it when I noticed that some of the fabrics are coming apart. I counted 10 blocks that would need bits replaced. I have fabric that I could easily use that wouldn't look out of place in the quilt. Also I've included a picture of the back of the top. Should I clip all those threads or just leave them be?
