I wanted something to cover the TV when we weren't watching it--I was thinking like this--but the budget wouldn't allow for anything "professional". So I bought a canvas and some paint and brushes and Sweet Husband and I danced on the lawn with it like wild paint pixies. (Truly, I think we were the neighbors' favorite entertainment for the night.) Two observations:
1. I can't remember the last time I gathered up a bunch of paint and just played with it without worrying about making something "good". Actually, I take that back, I do remember, and I was in high school. I painted a piece of plywood with my feet. It needs to not be ten years before I play with paint again because it was way fun.
2. Paint splatters are like cloud shapes. Upper left-hand corner? Poodle in a bow tie. Blue blob almost dead center? A ukulele. Years of fun, I tell you, years of fun!
