I usually go for the premium (200 ct) muslin. Legacy, Kaufman & Southern Belle are all very nice. They wash up nicer too than cheaper muslin. Not so many wrinkles. And they are a nice way to stretch out my stash of quilt shop quality prints. I can often find the Southern Belle on ebay for $3.50/yard. The seller is franks11. He sells in lots starting around 6 yd pieces. Shipping is fast too.
