I have fallen in love with Glide thread. It is a trilobal polyester with a lot of life. It doesn't make a lot of lint in my machine. I get it from BobbinCentral.com. I started out all cotton, not liking polyester, but then I got some at a quilt show. Love it!! The site sells wholesale and retail. If you try it, be sure to use a thread stocking. Ann
