I've been making my own neck straps out of scrap leather strips that I get from a friend of mine that's a leather worker. I like the thinner straps. A friend of mine turned me on to the thin leather straps. He shot a Leica M3 and couldn't see using straps bigger than the camera. The problem I had was finding a strong enough twine for the serving. I finally found some and it arrived today. It's a waxed (bee's wax) linen twine and now I finally have a wrist strap for the FED 2. I need to make some more. I hope I have enough twine.
