I was concerned that the pencil lines would not wash out. I sprayed with a prewash stain remover and threw it in the washer and dryer (removing it while still damp) and all was good. It did press out the major wrinkles so the quilting would show better.
- Someone suggested folding quilts on the basis to avoid fold lines. I opened the quilt to photograph it just before this post and still found some creases but in the long term, this may be less permanent.
