I was asked if I had any interest in equipment and material that was headed to dumpsters, the answer is/was YES! every time. It was about the time we quit making garments in this country and sent the jobs south and across the seas. Partial rolls of material, some were off white and the same material that was used to make cotton sacks. I lugged some of it home and started cutting patches, my wife took sympathy on me and introduced me to the the green board and the little pizza looking cutter, I stacked the material about 16 layers thick, In a short time I was so far ahead I may never use all of the patches, size? any size, shape? Round was not an option.
Bore snakes? Bore snakes cut down on the use of patches, not the commercial bore snake but with all that material etc., etc..
