Some friends of mine are trying to rid their kitchen of as much plastic as possible--buying/using only real glasses and dishes (no plastic, melamine, paper, etc.), eliminating paper towels and napkins in favor of cloth, and getting rid of all plastic food storage. I'm intrigued by this so my question is, what do you use for food storage? I have some Pyrex storage containers but these have plastic lids. Should I go for Ball canning jars?
