So I had this piece of dark blue corduroy that I had discharged with bleach some time ago. It has an irregular pattern to it in that the wales are different sizes. When I hung it up on the wall the other day, I could see a landscape in it, an abstract one to be sure, but still. But I wasn't entirely happy with the patterning and color.
