I consider muslin ( the good quality) to be a corner stone of my stash... its my go to fabric for soo many things. When I get a good deal .. I buy a bolt of bleached and unbleached. I mix it with everything from batiks to flannels. As others have said, do preshrink, it does tend to have more shrinkage. Even the "premium" preshrunk still has about a 3 percent shrink to it.
