These valances were the perfect color and pattern for my re-done family room/kitchen.  I needed 24 (lots of windows!).  No two were the same width!  I ended up laying them all on the floor trying to match ends so the disparity wouldn't be so obvious.  Sizes ranged from 18" to 19", with a lot of 18+" in between.  Many of them were 18" at one end and 19" at the other!  It was a nightmare, and I would never buy these again.
