I have an idea for those who are having trouble with stroping. I took a thin piece of wood, about 1/4" or less and cut it to the same width and length of my strop. I then drilled a hole in one end and put the board under the leather and on top of the canvas of my strop. In other words between the two and used the strop. I did not glue it to anything. It just is held with the leather or canvas on top when using. This prevents sagging of the strop when stropping.
