I have a fair bit of fairly high quality 3-4mm veg-tanned leather I got for doing some leatherwork.

Does the natural leather need any treatment or pastes or anything before I make a board or hanging strop with it?

I'm new to this, this would be my first strop; is this one of those situations where I should buy a ready made one first or is it ok to go straight to making my own?

Thanks,
Andrew
