Well.... unfortunately, my "work bench" is the kitchen table. Causes some degree of confusion...
I routinely have in-progress boxes & general mess at one end. Luckily, there are only 3 of us in the house, and (apparently) the wife is ridiculously tolerant.
And I keep most of my supplies (paint, tools, scratchbuilding material etc etc) in a cheap little rolling cabinet.
Spray-painting is done outside when it is warm enough, or in the basement near an exterior vent w/ fan pushing outside.
