Thread: making your own strop

hi guys, I know there is a lot of the threats about making your own strops, but I didn't find the answer I was looking for. I don't have a big budget thus I cant buy really expensive leather, as well as where I live I cant find any leather suppliers where I can go and hand pick leather. I have found an ebay seller with a lot of leather (they even make there own strops) but just wanted to check with more experienced guys from here would this type of leather be suitable.

24"x 6" ANTIQUE BROWN OILED VEG TAN LEATHER 3mm THICK SHEATH ect | eBay


that' are just 2 examples, it looks quite smooth to me just like a strop leather should. Is 3-4 mm to thick for a strop? All advice would be appreciated.
