This is an updated version of the Leather Bracelet I added earlier. The main difference here is the ability to adjust it. You can add a new 2mm hole using an Awl, Nail, Hole Puncher, or even an X with a blade. You can then insert the collar stub to the desired distance and make it permanent.
To save you time, this is the short video on how to piece this together. From start to finish, it won't take you more than 5 minutes to complete. Most of the buildout process will be in edges and burnishing the bracelet.
I hope you enjoy the build!
