I've been spending a bunch of time looking at the work other people are doing on Etsy. There are items posted there that I think are way overpriced, things that I could duplicate easily, but or the most part the work is much, much better than what I'm currently doing. I really need to practice more.
I thought I would link to a few of the stores on Etsy that I really like. These are also in our favorites list on Etsy.
Oh, check out Overnight Prints. They do buisness cards and other printing needs, and are very cheap.
