You need to use fairly large pieces and it's a lot easier if all of the corduroy is the same wale width. The UFO one I need to get back to is several different wale widths, which means different degrees of stretch on the crosswise grain, which can create problems if you aren't careful...hence mine currently in UFO status. Also I had tried to do it with 1/4" seams and narrow strips for part of it...NOT recommended!
Random large squares, big squares for a D9P, Around the World...all would be great...log cabin NOT a good plan!
