I hope this is helpful but when doing snake skins on a sheath it's best to keep the leather that you cut for the window. Belleville and trim then put it back underneath the snake skin so as the snake skin does not lay flat. This will cause contouring I think he gives it a much nicer look. I've laid it flat and found this is a much better look when done of course it's more work
These kits from Tandy Leather are really nice to work with and as you can see you're only restriction is your imagination they work better if you give them the Coat of neat's-foot oil the day before you go to work with them
I am new from California been doing leather work for a few years and wanted to show some of my work but have been unable to transfer from Android phone onto the site. Everything in my gallery and from of the camera are too large. I've been making knives and knife sheaths for years I also do bags done a few Harley seats I was so excited when I found this site but disappointed that I'm unable to download pics
