i only once put it in the dryer with a damp cloth. it came out all pilly. everything that touched it got bits all over. now i lay it carpeting and sprtiz until it behaves. it takes a while. if there are small areas that won't lay flat i (gasp) stomp it with my socks on! :twisted: just handling the big ones stretch them, and then having to deal with the creases is a real pain.
