Me and a this guy Mike I work with are collaborating on a project to make a custom backpack. He makes messenger bags, backpacks, laptop cases, and even jeans over at The Norman Porter Company, his a company he just starter with his brother. He is going to take care of all the fabric and leather work, and I'm making custom brass hardware for the bag. It's going to need buckles and other pieces for all the hard connections.
This is a rectangle ring going on the front of the bag
