I was proud to participate in the Rally for the first time a couple of weeks ago. The idea is the museum invites a bunch of artists to come in and draw for an hour- people can watch you draw. There's food trucks and other activities too. When you get done the drawing(s) are auctioned off for $50 each. All proceeds go to support the museum.
I was super nervous about the live aspect, having people watch me draw isn;t something I'm super comfortable with but since there were so many other artists doing it, it was easier. It was actually pretty fun. The piece above I started first, gluing the collage elements into place. While those were drying I worked on the one below. When I finished that I went back and drew on the top one.
I didn't have a strict plan, I just kind of riffed off of the collage elements I had brought- I wanted to keep it spontaneous because that's how I work best!
