Here is the cover I made from the tutorial. A word of warning: make sure you measure your camera strap before you cut your fabric. Although the writer of the tutorial said she had the same camera as me, apparently our straps were not quite the same length, so the first one I made was a little on the short side. It wasn't terrible, but it wasn't right and since it didn't take long to make, I whipped up another one.
This was made with a bit of fabric from my stash. You can also make a patchwork one from scraps, but since I'm not really a patchwork kind of girl, this one was better (and easier) for me. If you want to make a new strap, here is a tutorial for making a whole new cover from scraps (and an old strap).
