These are exceptional! You can not beat the quality and price of this panel. The polyester fabric has the sheen and slub of real dupioni silk. I purchased the teal and it is a gorgeous hue, closer to peacock blue or cerulean than teal (which is greener). There is a polyester flannel liner for insulation, blocking heat in the summer and cold in the winter, and a super soft, high quality cotton backing. You can create mock pleats by using the tabs or a bunch it with the pocket rod, which looks lovely either way. There are weights sewn in the corners so the fabric stays put.
