This is how I do mine. I get the cheaper roller shades in Family Dollar and take off the plastic.

I made the shades to just fit inside my windows thinking I would make curtains to cover the frame. Next time I will make them to cover the frame. I like the simple look much better.
Not so much fabric to collect dust either. And there is the little thing of rather spend it on quilting fabric. lol
