There are many similar cardholder out there but I drew the pattern for this one myself.
Made from a single piece (kind of a big T shape), veg-tan leather, hand dyed, and saddle stitched with linen thread.
There's a coin compartment, and another one that will easily fit 5-6 cards.
As always, happy to share any details.
For a second I thought I was on the 3d printing sub and was very impressed/confused
I can imagine haha!
