It's hard being a packrat when these weeks come along. I have a firm rule that I do not pick up anything unless I have a very specific use in mind for it and a place for it to go (and even then, nothing with upholstery—ew).
That's how it's gotta work. I have a tendency to be an incredible packrat. Got it from my parents; nature and nurture no doubt.
I use the same rule for any other clutter I come accross when I am cleaning. When in doubt, throw it out!
