How to make this flat?
So I bought a custom full grain leather wallet from a crafter. I been using this wallet since three months. But I am very much unhappy about this bulge. My OCD is triggering whenever I look into it.
In the first picture, there is 5 cards and one 100dhs bill.
In the second one 4 cards with one 5dhs bill.
So any recommendations to make it more flat and tight.
