This is about a 3' X 6" board salvaged from the college theater department. They'd made a bunch of backdrop pieces that they then cut up and threw in the dumpster. As you readily see this time I'm doing it backwards from my usual method. This time I'm sketching my design on the board first and then I'll do the faux finish on top of that. The danger of course is that your drawing could completely disappear and you'll have to do it over.
