I've made a 3D sheath for the first time.
It's leather is picked from a old sofa. :)
At first, the leather dampen for a while.
And the shape is formed by nail.
One day later...
the shape was fixed.
I sewed it by stiching tool.
Snap button and Waist belt strap were installed.
Leathercraft is hard, but rewarded. :)
