Electrathon, I used the template you had posted up quite some time ago and modified it for my first wallet. So, I wanted to give you credit for that while I recommended that Highlands does the same. Below are some links to the pictures of my first wallet. This was 5/6 oz with a pig skin lining. I cut everything to size, but I found that the 3/8 shorter on the inside wasn't quite short enough, so I just folded the whole thing up and cut off the bits that were sticking out past the tooled back. I can't find the link to the template right now, but it really did help me a lot. Sorry I can't offer much else in the way of advice.
