I had always bought my flint leather from Dixie Gunworks. Theirs is tanned buckskin. Not too thick. Recently I ordered some flint leather from TOTW only because I was ordering a number of other things. I recieved the order today. The flint leather was way too thick. I had to open the jaws of my new rifle almost all the way out (small siler) and could not get the flint back far enough for proper placement. Drat! So, I need now to order flint leather from DGW. Food for thought.
