I had the opportunity to consult with a creativity coach, Marianne Mullen at Awaken Creativity, so I thought I'd see what light she could shed on this issue. I must admit to a tiny bit of skepticism going in to the phone conversation. I mean, I've been doing art a LONG time, and what could a creativity coach see that I am missing? Asking for help is not always easy.
Now coaching is not therapy, so I don't know what deeper issues are connected to my seeming inability to work large. But Marianne absolutely NAILED the practical problems, and before the day was out I'd begun reorganizing a piece of my studio in order to work larger. I have a second-floor studio under a gable roof, so there isn't much vertical wall space. What there is is covered with my book cases.
So first I moved my book cases, which were between these two windows:




So I built a wall, leaving a little space at the top and bottom so that the space behind it isn't completely cut off from daylight. This is minimal framing, as the wall doesn't need to carry much weight. Again, I used homasote (primed) for the wall surface.



Just to be clear, I did not do this all in a day. I had my coaching session early in December and just built the wall yesterday. In between I did just a little bit at a time - got the homasote (cut the the desired sizes), primed it, got the 2x4 studs and cut those... holidays intervened, as did work... and so forth. One little step at a time (and there are many more ahead!), and I feel now that I have the tools to work large. We'll see what happens!
Marianne asked a lot of questions and quickly narrowed down my problem to something tangible and practical that I could start on TODAY. This coaching session was SO valuable, and I will definitely make use of what Awaken Creativity has to offer next time I hit a road block.
