I take a dial caliper in the fabric store with me.
USUALLY red stripe-.010,Green- .015,Blue- .018.
Make sure it is COTTON not synthetic.
I hand wash/rinse.Hang to dry.
I have a jar of lube recipe that I put the whole piece of material in.Take it out to let it dry flat.
I then cut with an old paper cutter.The kind with a long knife and inch measurements on the side table.Makes cutting and measuring real fast.Square or round patches make no difference.A scissors works as well. Pictures 659 by t410er, on Flickr
Patches are kept in glass jars to prevent drying out.When I carry to hunt I use 35mm film canisters.
The answers to all of life's questions are found in the Bible!
I've cut my own and or bought them pre-cut with butter already on. On the great Amazonian site they're pretty cheap, so why mess around with all the cutting and lubing mess. Wally Mart has decent ticking fairly cheap. I've recently ready that ticking is good for cleaning patches too..??
My local gun stores dont have .32 cal stuff. Its a 2 hr ride to Wheelng Cabelas to get patches so I had my wife stop at a fabric joint to get ticking. The stuf she bought is the blue stripped material and does appear to be cotton. Im going to wash it and check its thickness after drying. I believe the white patches bought at the gun shops are .015.
Yes should wash it and put in dryer it will tighten it up. It is all I use for patches. When at range and doing woods walks I pre cut and spit lube them While hunting I use pure mink oil. I typically cut like a 1 1/4 in squares for my 54 cal
