And why? Seems to me my all-time favorite was Springmaid, which I found in a quilting store quite a distance from me. I may go back there just to look for muslin, but have also been thinking of ordering online -- maybe 3 or 4 different brands in small amounts -- so I can compare them. With so many different muslins on the market, though, I'm not sure which would be the best candidates for an audition.
I still have some of the Springmaid here. It is closely woven, not thin, has a very soft hand and soft sheen to it -- really a delight to work with. I never was able to find it online when I looked, though. This muslin also came in subtly different shades of white and cream. Ummm.....I need to go dig that fabric out and see if there's printing along the selvedge. Maybe it wasn't Springmaid and that's why I've never been able to find it online....
