This is my pile on the floor, sorted by color of those fabrics that have "already been in the game"... The following 3 photos are the the arches, shown with the original fabric next to them, that I painted over to improve the contrast.
This is my wall this morning... I removed all the "corner" pieces for a better view of the arches. You may also notice a few switches took place also. In addition, there were 3 arches that looked a bit pale, so I painted over the fabric spires with a thin layer of paint to show the texture that was already there. They blend in much better now.
