Since I'm not actually a Graphic Designer, I'm not the ideal lecturer for this unit, especially for those of you who specialise in print media. I'll do what I can to help though, and when it comes to the Multimedia aspects of your folios I can be more useful.

Here are some online folio sites that may be of interest in generating ideas:

www.portfolios.com

www.electrofork.com (we have copies of their calendar in our sample box in class)

Some other cool portfolio sites thanks to Kara:

Glitter web directory - portfolio sites of artists, photographers, designers
