One key element in efficiently designing and drawing a show - not to mention other paperwork - is having an efficient office.
For me this means finally getting a theater carpenter buddy to build custom cabinets to hold specially-sized boxes to store drawings.
The standard for theater drawings is changing now as computer or CAD drawing becomes popular. (Earlier POST.) It used to be that a set designer would hand draw on 24" x 36" or larger paper, a size that is easy and cheap to store rolled. With CAD I've seen all sorts of weird sheets, many too small to roll well. I, myself, like hand drawing on 11"x17" sheets. These store best flat.
I've been keeping drawings in clean pizza boxes: Pizza Hut "The Big New Yorker" boxes to be precise.
Which all means removing every stick of furniture to replace cabinets under my layout table (and that table top too), then sorting through and reboxing every single file and drawing I've ever saved.
