Honestly, i plan on dabbling in/making everything and anything. Basically whatever i want or need that would require leather, or whatever i could sell. I realize that everyone says that at first, but its something ive been planning on at least experimenting with for a while.
Specifically at this moment, im going to focus on making knife sheaths of varying types, belts, holsters, axe head covers, axe shaft protectors, pouches, bags & purses, wallets, coasters, etc.
Eventually, id like to expand in to making clothing (especially period correct/reproduction clothing), jackets, vests, book covers/bindings, decorative pieces, vests, and even vehicle trim.
Im not exactly clear on what you mean by "tooling", though.
