I just started mine, but I'm using a report holder to keep the pages together for now. When it's "done" I'll probably get it professionally bound and duplicated at a Kinko's or something. I've gotten the photos printed on glossy 8x10's which is on the right side of the portfolio, and on the left side is the title of the look, a small face chart with breakdowns of the look, and a little information about the inspiration behind it, the model, etc. It looks kind of like a magazine type layout, but it takes a lot of work on photoshop to do that.
(which is why I'm taking so freaking long on it...)
