Until recently I have not been totally happy with the way I had been covering my frame for arched windows. I recently made 8 arched frame valance treatments, and by the time I was done covering all of them, I perfected a way that I was happy with. Follow along as I demonstrate how I covered the frames.
Cut a strip of lining as wide as the wiggle board and long enough to go around the outside edge of the frame. Staple lining to the outside of arch frame.
Using a nail gun, nail the wiggle board to the frame.
Staple the lining to the edge of the wiggle board
You are now ready to mount the finished treatment
The finished valance treatment is used to cover the top of the wiggle board
