I made a denim strop over the weekend and used it yesterday AFTER using the leather. Keep in mind I am a newbie, but I had the best shave that I have had to date. But, I also was messing with my angle a bit as well, so that might have had something to do with it also. I made it wide enough that I did not need to do an X pattern when stropping, and put a piece of steel rod in the top hem to keep it from cupping when pulled taut.
