I want to see the stitching so I am using a waxed white cord. I put a needle at each end of the cord and stitch back and forth around the hole pattern.
Before I fold the sheath in half, I add a welt made from 4 Oz. leather. It protects the stitching and adds a layer of leather thickness so the blade has room in the sheath.
Once cemented, I wet the leather with a small paint brush and stamp in a pattern along the edge of where the stitching will go.
And then punch the stitching holes.
Using the same white cord and double needle method, I join the two sides and the welt.
It's hard on the hands and a pliers is needed to pull the needle through but the end result looks pretty good.
With the stitching complete, I trim off the excess leather.
8 Oz. leather is pretty stiff but once wetted, It can be formed and molded like clay to the shape of the knife.
