Love these Curtains !!!   Have been searching for some Thermal curtains for the living room.  We live in N.C. so the sun is hot and summer is a long season.  We get the sun in the front half of the house from noon onward until 7PM ish.   so when I saw these I decide to order them and Hopefully they do the trick.  Well they DO THE TRICK !  Yahoo.  They are not very heavy, but they wash like a dream  and I did put them int he dryer on low (we don't have clothes lines here).  The important thing is they block the heat without being 3 or more lbs each curtain and they were reasonably priced  and I think I got a great deal  Thanks Wayfair for offering great product selections .
