Roc-lon perma press muslin - seeking advice
I will be using Roc-lon unbleached perma press muslin (403) for backing several quilts and possibly for piecing, and am wondering about shrinkage and if I should prewash it. Would love to hear from others who have used this muslin.
(Also, per the Roc-lon website, there should be "2-3% Residual Shrinkage" which doesn't sound like much to me, but I dunno. Is that a lot?)
FYI, I'm using mostly precuts so not pre-washing my other fabrics. Also will not be prewashing my cotton batting. I'd like to not have to prewash the muslin, but keep hearing/reading that muslin shrinks more than quilting cottons. I want to end up with soft and crinkly, not distorted, quilts!
