So, most of our bath towels are fraying badly on the edges where the binding is coming off, but they don't have any holes. I figure they have another year or two of wear left in them, especially if I redo the edges. Has anyone done this before and if so how would you do it? I tried googling; one suggestion was to just sew a double seam about an inch (or less) in from the edges and let them fray naturally then the fraying will stop at the seam. But what I am thinking of doing, something like applying bias tape (but it would be homemade, of course because the stuff in the stores is costly) all around the edges. However, I'm not sure what fabric to use. Cotton? Flannel? Something else? That would wear well and not be scratchy to the skin. How would I sew them on so they would look nice, without having to resort to blindstitching by hand on the backside?
