So I made two baby blankets and kept them both to 40" squares, planning to use flannel for backing. I bought some that coordinated nicely at Joanns. Now, I assumed the fabric was 42" wide -- maybe wider, but certainly not narrower.
I washed it, prepared for a little shrinkage...and now it's barely 40" and less than in spots. I can't use it for either blanket.
I don't think it shrunk by two inches; I think it was probably only about 41" at best before washing. Plus, the selvedge is a good half inch, and even bigger where the name runs up into the design. What a bummer. If I'd known, I would have bought fleece.
