I haven't tied a quilt for some time, but I wondered throught the yarn section of a shop the other day and they some sign up by some of their yarn~I think it was worsted weight and I didn't really pay attention to the brand, but anyway the sign said that this particular yarn the manufacturer had quit putting sizing in. So it is a soft yarn but ravels quite easily and they did not recommend tieing a quilt with it. Just something to beaware of. I know most of you don't use worsted weight for tieing quilts but thought I would throw this tidbit in.
