I'm not sure if Jo ann still has the high quality stuff on a regular basis , last time I was in they only had a lower quality , but they may have just have been out of stock. This one is 180 thread count they do have a 200 but I only saw it in bleached.
Ron Loc makes several grades fo muslin, so do be careful. They say the premium is preshrunk .. but I have had a little bit of shrinkage in the "pre-shrunk" .
