Wallets, Are They More Trouble Than Made Out To Bee

[AzShooter]

First pic is a The Counselor while second one is a Python.  Now I'm working with boa, leather and shark skin.  I'm using a 2 ounce. I'm using a 4 - 6 ounce liner.

My edge do not appear to  be straight  I'm on my third skin for a bi-fold but only my 2nd for Tri- ford;

Any ideas to help>

I'd start with different leather, such as Butero or Minerva, heck even natural veg tan, to get the hang of wallet-making before you start breaking out the exotic, expensive leather.
