Stolen from Talley Sue: Maybe put a dot (sticker? Sharpie? masking tape?) on every item and then
see what still has stickers after awhile. And use that to start a
re-evaluation process that -might- lead to a paring down.

Someone posted, somewhere, that they went through their pantry once a year and put a black slash of magic marker across the label ... the next year, anything with a black slash got another one.

It's easy to see what's not moving. And to make slashed items a priority for using up. And look at that can of anchovies with 5 slashes! Do you feel lucky?

Transient items that come and go within the year are not marked, just the things in there on pantry cleaning and marking day.
