Balenciaga Velo - How to Shorten Strap

Just a small tutorial on how i've shortened the strap on my Velo. This Velo is the Limited Edition Holiday Hamilton Leather. This leather is a little thicker and stiffer and than the normal slouchy Balenciaga leathers. So im assuming putting the little metal hook through will be less painful due to the softer leather on other Balenciaga bags. I hope this has helped.
