I am a big fan of the premium muslins (200 thread count). I've tried several brands and been happy with them. They don't seem to wrinkle or shrink as much. The brands I've used are Moda Bella, Legacy, Southern Belle, Kaufman Kona Premium muslin. I buy them when on sale. They do cost a little more than the cheaper stuff, but much less than regular quilting fabric is now. I usually pay about $3.50-$4.00 yard for it.
