I have been using Hobbs batting for a few years now and still love it. I do however put it in the dryer on fluff for about 20 - 30 mins and take it out right away and lay it on the bed to cool. Sometimes I will put in washing machine and soak for a couple of minutes and spin out on gentle and then put it in the dryer to dry. I do this if I don't want it to shrink in my quilt and have the old look, as I prewash my fabric. It all depends on what project I am doing.
