I recently ordered some 4-5 oz leather and it came in a few days ago. This a side, which is one full side of a cow.
I will be making a few minimal wallets and notebooks to begin with. I think I'll need to order a leather splitter since this is slightly too thick for a lot of smaller items.
I will eventually make a weekender duffle but will probably purchase another side for that.
And you call yourself a doctor…!
