Save Those Yogurt Cups

Yogurt cup greenhouses.

Yogurt cups of any sort make pretty good seed starting pots. They're about the right size, they're free, and you get bonus points for reusing something that would have been thrown away.

YoCrunch cups are even better for starting seeds though. The raised, clear lids make a great little greenhouse.    The beans we planted in these came up in record time.

What are some things around the house that you've found a good second use for?
