I repaired a quilt that was at least 50 yrs. old for someone. It had been bound by wrapping the backing around to the front. The binding wore thin right at the fold on the edge of the quilt and eventually started tearing on that fold. So my main repair work was trimming up the edge and replacing the binding. I think the problem was the single thickness of fabric. I would suggest, if you want to wrap the backing around to the front for the binding, cut the excess backing fabric enough wider that you can fold the binding part in half and to make the part that wraps around the edge a double thickness of fabric. I think it would be less likely to wear thin in years to come. It would depend on the use of the quilt. For a wall hanging or something more decorative, single thickness would probably wear okay. I quilt that will be drug around and much loved, as this one was, would need two thicknesses of fabric to prolong the wear.
