Hey, has anyone ever tried to sew a window treatment for an arched window? I just moved into a new home (yay my first!) and it has a half moon type arch above the living room window and it faces the west (yuck afternoon sun!) Right now I have a piece of foam core (yes how attractive) blocking out the light above the vertical blinds covering the rest of the rectangular portion of the window. Ive tried to find patterns for a window treatment for this type of window, but have been unsuccessful. Does anyone have any suggestions? Thanks!
