I have purchased these shades from J. C. Penny, and am very satisfied. They come in many sizes and 10 colors. A blackout layer sandwiched between 2 layers of vinyl helps to block light and give privacy. You can also get them in fringed (Scalloped bottom hem) or unfringed(straight bottom hem). A heavy duty spring roller mechanism makes using very easy to put up and down. You can order either inside or outside mount, and the hardware is included. They can be cleaned by wiping off with a damp cloth. Usually the price includes a discount if you buy 2 or more. The only downfall is the shipping, unless you can get codes or coupons from J. C. Penny, for free shipping.
I have tried these and like them. The sun shines in our bedroom in early morning and we needed something to block it out. We made a good decision to go with these and the price was right.
