I have hand quilted several quilts. One queen size and then smaller ones. I wash them in the washer in cool and dry in the dryer. I’ve never had a problem with them. Funny story - the oldest grandson was a little boy and came to visit and I covered him with that queen size quilt and told him I made it and hand quilted it. I don’t think he knew what that even meant. He said “wow grandma - it looks boughten” which I decided to take as a complement. He is almost 21 now.
