A couple of drops of yellow food coloring and a few creepy objects like these eyeballs and spider and in seconds, you have a "mad lab."
Or, use green food coloring with a skull or a toy rat.
A black pitcher or vase with twigs sticking out can look spooky.
If you buy pumpkin decorations with a jack-o-lantern face on just one side, you can use the jack-o-lantern side for Halloween...
And then turn it around and use it for Thanksgiving.
