I buy the red striped pillow ticking at Walmart. Wash it it to get the sizing out of it. It measures .015” thick. I then use a Fiskars roller cutter and self healing board to cut it in strips about 1” wide. I cut the fabric so it’s 18–24” long before cutting the strips. Roll em up, rubber band 2-2.5” rolls. After pouring in powder, put strip over muzzle, lube with your choice, set ball on, button starter to seat in muzzle, cut with knife, fully seat charge. Some grind the teeth from circle drills and cut round patches. The blue ticking measures .018-.020” thick. Joann’s #41 drill cloth is used by many. Good luck!
