I just looked up the website and it looks like a really new high-tech product for machine quilting.
Have you tried their Premo-soft? It says it can go from piecing to long-arm quilting, plus it can do serger and bobbins. It has a matte finish and looks like cotton. And it makes your 1/4" seams perfect too!!! Kidding on that one. But it sounds terrific. It is spun polyester.
Oh oh the quit police will be after them for not piecing with cotton!
