Six foot wide easel somebody wants me to make (for painting 8' wide paintings).

I do all my thinking on paper, making Leonardo notebook-like sketches to realize all the problems before I start cutting up wood. I must say, drawing is supremely satisfying; more than actually making and delivering the thing, I'm sure. It'll be 7' tall, have collapsible wheels, and be easily assembled for use, and disassembled for storage.
