Sometimes I'll make multiple .bmps--ms paint-- for one room, depending how complicated it is, as well as different concept variations. Also will dl and save relevant ref pics.

loads in the pure planning stage...

For this compo I had two different Ideas, and different variations of each Idea. It was actually a lot of fun planning it, but unfortunately, I never had time to flesh it out.
