I got a new gun and needed some material for patches, in the .014-.015" range. The ticking at Wally World all ran about .018-.019" and the stuff at Jo-Anne Fabrics was a whopping .022-.024". I was cruising the aisles in Jo-Annes, looking for an alternative, and came across some stuff call Cotton Sateen, used for lining drapes. It is a very tight weave 100% cotton and has proved to be exceptional. I have been using it to launch .600" balls, pushed by 80 grs. 3F, from my rifled .62. I have picked up some of these patches and used them again, and could have used them the third time, they were in such good shape. It is a little more pricey than ticking, going for $5.99 a yard, instead of the $3.99 a yard for the ticking. The price per patch worked out to 3/4th of a cent for me, much cheaper than paying $4 per hundred commercially. If you have access to a Jo-Anne Fabrics, and need .015" patch material, give this stuff a try.
