I finished the offset square quilt top which I am delighted with and would make another one any day. Now I am tieing the center of each pinwheel with yarn. How do I keep the yarn from fraying. I read a blog that said fraycheck because it dries clear and soft. Well it does dry clear but never ever used it that it was soft. I tried one piece of yarn and it is too scratchy when it dried for my desires. Any recommedations would be greatly appreciated. And maybe when the quilt is washed it would be soft on yarn I just don't want to chance it without your wonderful responses.
