I pulled out a couple of quilt tops that a put together years (10?) years ago. I started to hand quilt one of them. I discovered that the seam to one of the blocks is coming apart. Tried to sew it back together by hand but it kept fraying. Put my problem on the QB. I have all the things that I need to fix it, but I'm scared to pick it up. :-( I don't want to ruin it. Every time I look at it my mind goes crazy. What do I do? :?:
