I prewash every piece of fabric that crosses my doorstep, even/and especially fabric given to me by others. When I wash my quilts after they've been finished I still get the crinkly look. I had a red and white dress many years ago that when washed was red and white striped. :lol: I have washed everything since. I don't like kits bc sometimes the itty bitty pieces shrink to a hand full of thread.
