I absoutely hate the stuff. I bought several spools and after several tries using it, gave it to a friend who loves it. She used it to make a sweatshirt jacket and the ends of the threads are like little wires that stick you--inside of elbows, back of the neck, etc. I certainly would not want to use it on a quilt that I wanted someone to cuddle with. But if the object is to make the thread as inconspicuous as possible, monofilament is the thing to use.
