If you’re looking for an alternative to replace the ugly nylon strap of your camera (works with modern digital camera or old film camera), then you should have a look at this DIY Camera Wrist Strap project by Wood&Faulk. The finalized design is one piece of leather that wraps around and through its own scratch guard. These are made for cameras with a lug mount, and the split-ring will be supplied.
If you’re interested in ordering, make sure your camera will work with the strap, as it won’t work if you have a loop attachment point on your camera. More information is available here.
