Hi, just wanted to thank everyone for the nice comments. It really helps keep me going!!
I did cover the raw edge on the back of the shade. I folded a hem in the same fabric as the shade, as small as fold as I could, and pressed with an iron. Then I cut the fabric away from the larger piece, it helps to fold the hem if you are still working with a larger piece of fabric. I cut a narrow piece, then I folded a hem on the other side of this narrow strip and glued it on top of the raw edge on the shade. It looks like you've put a piece of fabric on top, but it's not a raw edge showing. My fabric was cut on the bias, I don't know if it needs to be on the bias, a piece cut on the straight grain could work just as well. Talk to you all later, Kris
