I ran up against this just this past weekend. I made a quilt with a jelly roll. So after it was completed (top only) I threw it in the wash. Only soaked it for a minute, then into the dryer. I don't like the puckered look at all. Next I threw the dark red boarder fabric in (three times) to get it to quit bleeding. Then in went the batting, Hobbs Heirloom 80/20. Batting in the dryer on air, but then low because it wasn't getting dry.
