The wife and I are both surface coverers. The desk in the living room, one particular counter in the kitchen nearest the door in from the garage, my desk in the basement, and the benches in the workshop are all covered to one extent or another. We manage to keep the table in the library open, and we've gone almost religious about keeping the dining table clear, but anywhere we work tends to pile up.
It's difficult. There are probably five projects' worth of stuff on my main workbench, including some air fittings from at least two different air projects, my small parts sorter thing, my battery chargers for my Craftsman power tools, some of those power tools, a disassembled computer power supply that I was extracting a capacitor from, a couple of soldering irons, a bunch of screwdrivers, electrical parts bought for various projects, an arbor press that needs to find a more permanent place, a benchtop drill press in a similar position, and a bunch of other stuff that I can't remember off hand.
A lot of it comes from my inability to find homes within the workshop for some of this stuff. Once I manage to do that then it'll be easier.
