Thanks for the link.
Yeah, I stumbled upon that thread before I became a member, been studying it ever since. Pretty informative.
It's the actual material/leather that i'm not a 100% with. Don't know which are just tanned, dyed, veg tanned at such.
The leather supply store I go to doesn't always have informed staff at hand. I'm just winging it at the moment... buying scrap leather for practice.
