It's probably similar to the 100% cotton Mountain Mist Blue Ribbon batting I sometimes use. Love that batting. It is very thin and soft and gets even more soft with every washing. It is an old-fashioned batting so there is no scrim or chemical bonding agent in it. It's not necessary to totally remove wrinkles; they never showed in my finished quilts anyway. There are a couple of things you can do to get rid of the worst of the wrinkles. You can drape it over a table and chairs, mist with water, and let dry. If you have a large dryer, you can mist with water, wait a couple of minutes so the water absorbs, then tumble in the dryer for 10 minutes at a time. Some modern quilters don't like this type of batting because the results are so thin, especially compared to the thick comforter look we are all used to now. However, that is what vintage quilts were made with. If you ever have a chance to handle a vintage quilt made with cotton batting, you will discover that those quilts are very thin and soft. They also shrink with washing, giving the "crinkled" look that some quilters don't like. Personally, I love that vintage look and feel. Keep that look in mind, though, when choosing a top to quilt with this batting. A really modern top might do better with a polyester batting that doesn't shrink or crinkle.
