I've knit a couple things out of the Knitpicks Gloss, and it's just lovely. I really want these to be cotton. I had assumed that the Curio would be like the Aunt Lydia's cotton, but I guess I could gauge some #10 cotton I've got to see whether that makes gauge and then try ordering some of the Curio. Come to think of it, the natural #10 Aunt Lydia's is not as hard as the colors I've used. I wonder what the white is like...
