I do avoid pre-cuts, for several reasons, and not being able to pre-wash is one of them. (Other reasons? Inaccuracy in some of the cutting, higher cost for some.) I don't mind doing my own cutting, even prefer to do it, and I don't typically use patterns that are geared to pre-cuts. I'm also not a matchy-matchy type, prefer to select my own fabrics from stash rather than use all the fabrics in a designer's new line. Yet when I see a quilt that someone has made from one of the new lines, I am the first to ooh and aah over it. The designer selections make gorgeous quilts, but that's just not my "thing".
