I decided on a bull skull with barbed wire border for either the knife sheath, the holster, or both. Practice was important. You can see that getting the barbed wire to line up is not as easy as you might think. The skull will need a LOT of practice. The guys in the videos make it look Really Easy.

Next I just worked on the various border patterns. Practice might not make me perfect... but it WILL eventually improve the looks of my borders, from Hack to not drawing the eye to my mistakes.

Next up, to break the "Bore" dom I tried another Maple and Acorn pattern. First you transfer the pattern and carve it into the leather.
Then you do your tooling and dye it. I used yellow, red, and brown dyes. Not real good at it yet, but I gave 'er a shot. Then set it aside to dry overnight.
