Sure, ask me a hard question. :D
Here's what I know: I'm not sure on the weight. It's about 1/8" thick and vegi tanned. It was fairly stiff leather. The dye was an alchohol based chockolate brown and the sealer was Tandy Super Sheen. The laces are latigo (for durability).
Basically I went to the tandy Leather store, talked to them for a while, told them what I wanted to do and took their recommendations for products. Outside of a simple knife sheeth this is the only thing I've made.
I tend to be on the crafty side but I'm just learning so I admit I'm a little clueless as to what I'm doing.
