Ok...so I'm now pre-washing every piece of fabric that comes in the door. I've done this off and on for years and have a good stash. The puzzling thing for me is now how to tell if it's all pre-washed? I don't cherish the idea of having this same question come up in the future.

Do you have a better idea?
