Try consolidating two households into five storage garages, then taking up a huge bike collection and moving twice in 3 years! OY!
I also work on a few bikes at a time, because I'm always waiting for parts. In any event, although I have a decent work area in the basement, I like working outdoors when the weather is nice, so that complicates matters too. I find big stainless steel kitchen bowls that you can pick up at garage sales for $2 are the best parts solution when stripping a frame. Better than ziplocks for sure. Toss the parts in the bowl, run the parts through the ultrasonic cleaner, and keep going.
I liked Robbitunes old signature, "It was here just a minute ago."
