Easy, cheap and it looks really beautiful!
Made the valance to match wit the Wall Picture Display for my daughter's room.
Cut the ribbons about 20 inches in length. For this project, I used 2 rolls of 1.5"x4yds each(polka dots), 2 rolls of different colors of 1"x15FT and 2 rolls of 5/8"x15FT.
Bought the ribbons at half price at Hobby Lobby. Spent $8 for the ribbons.
I added some wall stickers from the Dollar Store above the valance.
