So immediately, the next day I went onsite with a private student venturing out into her first plein air adventure . . . and you guessed it! Where did I paint? Right in the space I needed to save. Here's the gurgling Lithia Park Creek, sitting right where I wanted to have white space. I fretted and pondered about cutting out the image, inserting a full page and on and on.
I continued my journal sequentially, with the sketch from a "Plein Air Workshop" I was teaching. Top left on the full page, is a sketch of my dear painter friend, Silvia Trujillo (http://www.silviatrujillo.com/), (who'd instructed the oil students) posing her hand to crop a portion of a student's painting during critique. Farther down the page is one of my watercolor students busy at work.
So I can attest to the fact that mistakes can make me more creative and inventive. Honestly, I have to say I've not gotten to the point where I celebrate errors, but I DO aim to get there some day. Another goal to aim at . . . it keeps me going and getting more comfy with myself.
I suggest "Celebrate Your Errors!"?
