This post from Lara Cameron of Ink & Spindle is full of great tips (and comments) for starting a small craft/design business.
Lara's Christmas card design for Moo.
I told myself that opening an Etsy shop would be a nice way to keep the flow going. The idea was to have fun and not get uptight or over-think. But my character flaws emerge regardless of context, so I've put off opening forever. I'm frustrated with myself, but that's even more time wasted. Better to just move forward.
