Watterstide: "i have never prewashed batting, and have never had a problem with it either..i use W&N about 90% of the time.
I always use a color catcher,if i am uneasy about the quilt colors bleeding.better safe than sorry.
I have used loads of charms and maybe a half dozen or less jelly rolls, and have never had a problem with them bleeding. Never. all were Moda,i believe."
Maybe I need to go W&N, too. Nice batting I've used it a few times but if it behaves without pre washing - that's for me.
Thanks!
