I couldn't get the video to load, but I love having a business facebook page. I don't pay for advertising on facebook, but posting behind the scene pictures, things I like, and press info (blogs that feature me, giveaways..), builds a connection with people interested in my work.

I did the facebook advertising once, when I first started out. I think I gained like 5 likes, but that's about it. Not sure i'll pay for facebook ads anymore.
