My new to me ZJ's PPO had a dog that ate the original seat belts. I replaced them when I got it but kept the old ones. I wanted a new strap for my Nikon so I used a piece of one of the belts. I used some of those plastic disconnects so I could remove it when on a tripod. Seat belt + history professor elbow pad + para cord =

That larger disconnect hooks to the strap and the other end hooks to my belt so the camera is tied to my side when I am on a bike.
And the resultant mess:
Next will be a wrist strap.
