Holds 3-5 cards or more depending on how much stretch your leather can take. Once broken in, it will hold more then the initial amount.
This design takes inspiration from other card holders and other leathercrafters work. Due to this, I am putting it up for free for anyone to use freely. Most notably inspired by one of Corter Leather / Weaver free patterns, the flap card wallet. I made changes to their design to best fit with what I was going for.
Feel free to check out his youtube video on his wallet build which can help build this design. Link
