First art fair! Quite convenient because it cost five dollars and it was a whole two blocks from my house. It was a good low stakes trial run. I bought the beige Pro Panels (wish I could've found black) used on craigslist, bought a new pop-up canopy and brought the photos I'd already had printed – mostly lightning/storm photos. I even sold one. It's kind of fun to think of my work hanging up on someone else's walls and them enjoying it.
I've got a list of improvements to make, but I'm comfortable enough now that I'm going to start applying to more high-end shows. I'll need to do a few of those to see if the art fair route is going to be a viable avenue for selling photos.
