I've been meaning to post this for a while, but here's a veg tanned goat skin bullwhip I made a while ago:
Like I posted earlier in my opinion it's not as nice as kangaroo and very stretchy, so cut wide! However the whip that I made with it is a solid whip.
This was made with the veg tanned goat from Tandy which is dry, so I had to had stuff it with dressing before I plaited with it.
