Continued from Bushcraft Knife Sheath Part 1
When you get back to the starting stitches, you'll encounter some resistance. The first holes you stitched are going to now be tripled stitched. These are tough, but pull the need through with pliers. Make the last stitch end one the back-side.
Here I applied some gum tragacanth to the edge and "slicked" it with a wooden dowel.
After the forming, dip the sheath in neatsfoot oil. I have used Dubbin in a pinch. Others have used SNO-SEAL.
Good luck in your sheath making adventures.
