Knitting along selvedge

I am knitting a hat that is flat. I had to bind off but I have to pick up and knit 68 stitches along selvedge. I do not understand how to do this. Does anyone have any suggestions?

There is a video here in KH about picking up stitches. That should help clear up any confusion, but ask again in this thread if you need more help with it.
