Wallet card slot assembly - construction techniques and properties

I am most proud of the construction of my card slots. I use a a special method of construction that is very time consuming, tedious and rarely done. It is required however to make a wallet that will be beautiful and luxurious. 

I line all surfaces of my wallets so that there is no scruffy flesh side of the leather present and these card slots are no different. They are made from 1 piece of folded leather each. This allows for the strong grain side of the leather to make up both the outside and inside of the card slot, as well as the top edge, so that it will remain beautiful with use. If the card slot edges were painted or burnished, they would become ragged with use.

To further enhance the appearance of the card slot banks, I carefully carve out the backside of the leather where card slots will overlap. Through this technique, there will be no unsightly gaps between slots and the edge of the wallet will be flush, not lumpy.  Above is an image showing the indentation created where the second card slot will be affixed.
