I made a quilt for my sister out of charm packs. i didnt wash them first. My other sister says it will get all wonky when it is washed. Are you saying when you get the charm packs that you dont have to wash them? I was going to tell my recipient sister to wash the quilt in cold water with vinager and hang dry just in case. this is my first quilt so I know I have made lots of beginner errors.
