I was never very fond of the camera strap that came with my DSLR. Black and yellow and so stiff it cut into my neck. It was also a bit short so that the camera landed in an awkward spot.
Here's a link to the tutorial I used, minus the lens cap pocket. The hardest part, believe it or not, was finding the right dog collars for cheap $$$. I didn't have any fusible batting so I just used regular batting and I also left out the stiffener; after all, that was one of the reasons I didn't like the old strap. I made the new strap is a bit narrower and when I make a new one (there is leftover fabric) I will make it according to the tutorial.
