JoAnns Fabrics has them in pearly white, black and some others, if I remember
correctly.

You can get a pack of 5 yards for around a dollar. They also have a couple of
sizes, too.

A lot of times they have them in the clearance bins for 50 cents each.

My wife is a quilter and I usually go to the fabric/quilt stores with her. You can really find some good stuff there.

Ray, let me know if you don't have a JoAnns near you and the next time we go (up in Oklahoma or Denton area) I can pick you some up.

Have fun,

George
