I've been thinking about your problem for the last few days, BriDean. I know it would be lots of work, but maybe the best solution would be to re-tie the quilt and then remove the original ties that are rough and sharp (or remove the ties and then re-tie). Altho it would be time consuming, to me it sounds easier than using acetone and scraping on all those knots. Then you could use the "surgeon's knot" or "square knot" that Carol suggested and you wouldn't need a sealer. Just a thought.... Anyway, everyone of us has learned something the "Hard Way" and shared their experience here on the Forum to help keep the rest of us from making the same "mistake." Sometimes the learning experience results in an unexpected improvement or creative result, but sometimes it just has to be redone. Only you will be able to determine if that is the best solution for you...but we will all learn from your experience with the Fabri-Tac, and thank you for letting us know!
