I took some classes at a drapery school in North Carolina along time ago.
They are very easy. I can email you some instructions. A really neat idea for them is to only put a row of rings down the center. Your wieght bar at the bottom must be cut in two pieces. When these are drawn up, it makes a fan shape (or a Half circle) at the bottom. Really easy and looks neat, and you don't have to sew on all those rows of rings. PM if you need any more help. Linda
