The possibilities of slipcovers you could make are endless. There are some adorable ones for purchase on Etsy, so if you don't know how to sew or you don't feel like taking the time, check them out! I didn't really want to spend the money on a slipcover, though. So making my own was perfect because I coule make everything just the way I like it! :)
So if you are interested in sewing your own slipcover, check out this tutorial on how to make a ruffle camera strap slipcover: http://www.kevinandamanda.com/whatsnew/crafts-projects/make-a-ruffled-camera-strap-slipcover.html. You can always do something different then ruffles (fabric flowers or ribbons would make a cute decoration).
The whole project didn't take too long, and it was totally worth it. The only thing I changed from the tutorial was I made my ruffles a little wider so you can't see as much of the underneath fabric. If you end up making one I would love to see pictures! :)
Next on my list of "camera projects" is to make a camera purse. Here are a few pictures of how my camera strap turned out:
