Gymgirl: Great tip! I haven't done the dry cleaning thing since my work days long ago, but I do like the idea of recycling plastic bags for this purpose! I've used the clear plastic bags my daily newspaper comes wrapped in for small containers and I've recycled and used 1gal and 2gal zip lok bags also. Just be sure to wash and rinse the zip lok bags thoroughly to remove any food residue if they've been used previously for food storage.
