Post pictures of any shopping bags you have (i.e. bags with store/company logos on them when you purchase things, not tote bags you happen to use for shopping purposes). Anything from grocery bags to fancy shmancy boutique or department store bags with the tube handles.
I'm a packrat, so I've been amassing a bunch over the years, both for collecting and recycling/reusing purposes... but, of course, I hoarded SO MANY that a lot of them just ended up getting old and gross and dusty, and so I had to throw a bunch away... but not before taking pictures of them. :D
