The real trick, and this was brand new to me, how do you get this 8 1/2 x 11 sketch onto a 10 foot by 20 foot backdrop. My wife, Reine, saved the day with an awesome solution: copy the sketch onto a clear transparency and use an old time overhead projector to project the image onto the backdrop. Shazam! We had it laid out in less than two hours and the painting could begin.
