thanks for this Barra, it helps alot. I have a side of what I think is called "bag leather", I got it from Packers a few years ago when I was toying with making dog collars from cow hide, that's what they sold me. I dont like it but do you think it might be OK for this? It's unstained, quite thick, well, a hell of alot thicker than roo, but fairly flexible and has some stretch in it.
