I pre wash everything except thread lol! That said, I take the batting out and put it in hot water in my top loader, some soap, let it soak overnight. Then I drain and let it spin out. After that I put it in the dryer on high heat. So far it has all turned out just fine. Some things are fine for the crinkly look, some I don't want that. I don't do a rinse cycle on it because after I finish with a project I wash them anyway.
