Who couldn't use a few extra trash cans around the house? If you are hosting a party or a big event, they can really come in quite handy. However, you probably don't want to go out and buy a bunch of trashcans. The simple way to avoid this and still get trash cans is by flipping some bar stools upside down and attaching a trash bag to them, securing it.
This will give you an almost endless supply of "trash cans" without ever having to go out and buy new ones. It is a simple and inexpensive way to host a party.
