I slap mine in newspaper and an old Safeway bag. For bigger items like teapots, people get two full sheets of newspaper, for mugs you get a half sheet of newspaper. I have hardly any plastic bags anymore as we try not to bring them home from the store. Lots of people bring a re-usable cloth bag to the sale.
Its about the pot, not about the package. I am selling from my studio, maybe I would get unprinted newsprint if I was in a four day sale.
Remember to reduce,re-use, and walk softly on the back of Mother Earth.
