I'm not scared of putting colors on canvas. But I am nervous about painting my walls a new color (subtlety is not my strong point). So I've hoarded paint chips over the years, along with all the crazy/wonderful color names. In the hope of creating a cool collage, I cut a bunch of them up with deckle-edged scissors. The collage was a bust. But the remaining names looked really fun. so I keep them in a little box on my desk -- for "Paint Chip Poetry".
Here's how it works: I pull out a few chips at random and force myself to make a cheezy story about them, e.g. The sailor with a Grey Beard and a voice like Cracked Slate secretly collecting Water Irises as a hobby. Not even close to poetry, but a great way to get my mind un-blocked so I can move to the next task.
Whatever it takes to keep the thoughts flowing....!!!!
