Where did you hang them?
I had given a quilt to someone and when I went to visit and she laid it out on the guest bed it was clear that it had been folded up somewhere for months as it had a big crease down the middle. I kept trying to massage it out but it kept wrinkling back up.
It was not W&N - it was the super-light super-thin Quilters Dream stuff.
I was so sad - it really looked awful!
I would have put it in the drier - glad to hear that that works!
