I have a guy that wants a ww2 holster with flap. I have made several holsters using 7,8,9 oz veg tanned leather. I have made him at least three. I always line mine unless instructed otherwise. He wants one with a soft lining and I'm not sure what to use or if it can be done. I usually use a 1 to 1.5 oz pig skin to line. Any ideas would be greatly appreciated.
