How to make a key holder with leather? 

First, you will need about 1 square foot of leather. We recommend using thicker vegetable-tanned leather with a thickness of around 2.5-3mm to ensure a firm and durable texture. Next, use our Babylon Leather Key Holder Pattern to trace and cut out all the necessary leather pieces. After cutting, punch holes in the leather with a recommended spacing of 4mm. Then, finish the edges and surface of the leather. Finally, sew and assemble the pieces, install the magnetic snap hardware, and adjust the shape. The finished product measures 8.5cm x 6.2cm x 1cm. Once completed, you'll have a high-quality leather key holder that can last a lifetime, uniquely crafted by you.
