How to make a car key case? 
Craft a charming Leather Car Key Case with our pattern, featuring a cartoon design. Using approximately 1 square foot of leather, this pattern creates a finished size of 8.5cm x 11.5cm x 1cm. Punch holes at a recommended 4mm spacing and assemble with Keychain and Leather cord hardware. With an estimated completion time of just 2 hours, follow these steps:

1. Prepare the leather.
2. Cut the leather using Babylon's pattern.
3. Punch holes and treat edges, adjusting the surface per leather type; typically, veg-tanned leather warrants surface treatment, while other smooth leathers may not need it, and fog waxed leather simply needs a wipe.
4. Prepare needle and wax thread, and sew.
5. Assemble the hardware and shape the case.

You'll then have a cute car key case, which can also be used as a daily key holder.
