This was my first try at a ccw holster. I am getting better at actually making things and want to learn to finish the edges

Why water instead of Gum Tragacanth?

Actually I'm not sure what it is. If it isn't vegtan then how can I finish the edges

I am just getting started with leather work I have made a couple holsters but never tried to burnish the edge. The scrap leather I got isn't dyed all the way through. Can I darken the un dyed part with burnishing or do I need to dye it somehow. I like darkening the veg tan leather I have used for other projects with vegetable oil. But I don't think that would darken it enough to match the top layer. Any help?
