LOL Cotton...I had to look at your location. I was really surprised to see PA when you said you "need" grits! I'm southern and even I don't need grits! LOL!
Mousie, I've never felt like I needed to iron my quilts after washing with the W+N. I like the crinkly look most of the time. If you do heavy quilting, it doesn't matter anyway since it can't do much shrinking. If its important to me that I don't have any shrinkage, then I'll use a poly batting. I'm going to try wool for my next one though, I just want to see what happens.
