Years ago, in some magazine, I saw a Log Cabin done in corduroy. It was just one solid color fabric, (beige as I recall) and the way it was layed out, the "nap" made it look like a dark and light side. Very striking. I may still have the pattern, but never made it! You would have had to be very conscious of the cutting to make the nap lay correctly. So, guess you could use corduroy in a quilt, but I'm not inclined to do so.
