Some people say they won't prewash fabrics because sometimes it goes "wonky"
If fabric is going to "go wonky" - wouldn't you like to know BEFORE you put it in something you plan to make?
Are the cuts a full 18 inches long now? I bought some several years ago, and most of them were less than 18 inches long.
(I've had skimpy-short cuts from OTHER places as well - including vendors at Quilt shows)
