Since I had to figure this out on my own, I decided there should be a post about it.
If you are on Ravelry, and want to add some progress bars that link directly to your projects inside of Ravelry, all you have to do is go to the Api page. (sign in, go to http://www.ravelry.com/help/api)
ta da, now you have progress bars.
I haven't bothered to really mess around with the look of the progress bars. I was just ecstatic to figure out how to get it working. Cheers!
