Do you dye the flesh side of veg tan?

[Chitin]

I've been dying the backs of my collars, then coating it with gum trag and burnishing the heck out of it, then sealing heavily with the "sheen" of my choice. It seems to have worked so far: I've done experiments with little pieces of scrap where I put it under running water and then rub it on stuff and it's done okay. Maybe I've just been getting lucky.

For my masks I just leave the flesh side raw. It's nigh impossible to burnish a concave surface.

I use the pro oil dyes, by the way, and I'm gradually making the switch over to the eco-flos.
