What an excellent question. I just wondered this the day before...I would think if you prewash it the nice folded edges (especially of double fold) would come out...and that's what you buy it for:) It probably depends on the project - like will it ever be washed or not. I'm anxious to hear what others say.
I never have, but I'm not sure that is the "correct" thing to do or not. It's never caused a problem for me. I'm curious to hear the advice from others on this.
I haven't washed it in the past and didn't have a problem with it shrinking, BUT I did have a problem with the colour running... This might just be my luck, though...
I never do that and have not had a problem (yet!)
I love hearing from my readers - thanks for leaving a comment!
