All my sheaths so far have been for my own knives, so they are part of my learning process... the first was very simple, the second had some tooling, the third, I tried several different things all at once.
Since my dad is a big pheasant/quail hunter, I think I will inlay his with a piece of blaze orange and tan canvas like the sleeve of a shooting shirt, and then use orange G10 plus a light wood on the scales. Should be eye-catching, if I can match what I have in my mind.
