I bought quite a few yards of fabric that came off a roll of a thousand yards. This was used to make draperies and bed spreads for motels. I used the fabric for the back of the quilt on my bed. It didn't take long for the fabric to "pill". It was covered in the little pills and they were hard. Many years later, I acquired a fabric shaver, used to take the pills off sweaters and such. I decided to try it on my quilt. What a wonder! All the pills are gone with just a once over and they have not returned.
