I have seen a lot of videos about stropping on youtube and i think i have the idea but the question is not about technique but about the hardware.

i bought a strop 3" at SRD and it comes with leather and the other strip is fabric, as i said i know, more or less, how to use the leather one but waht about the other, its not linen or canvas is fabric, and how do i suposse to use it and when? and waht about the back side of the leather? is it useable to paste with some abrassive?

Thanks for your advice guys
