I recently had to remove 11" of a quilt. It was for someone else and there were lots of triangles and a new quilter. It looked very bad so I separated the top from the batting--using a single edge razor blade and putting a little tension was able to remove all of them in about an hour. She believed the batting to be Warm N Natural but I don't know what it was but it did lay flat and I knew that a poly would make it puff up instead of all those tucks. It did turn out well with very few tucks. Thank, God! I used masking tape to remove the loose stitches and tweezers for the difficult ones. I did not pre-wash because I didn't want to deal with all the fraying. I'm fairly new to this but would post a picture if I knew where except for the gallery.
