I did go through and clip the threads, they seamed to be catching on everything and it gave me a chance to look at all the seams on the back and I may be replacing a few more patches. Any advice on how to replace them would be appreciated! I'm not all that keen on cutting out the frayed pieces in order to sew a new one into the space, but I've never done any applique, which I'm thinking might be the easiest way to go. I do have a quilting hoop if I would need that for appliqueing the new pieces on.
