Whenever my kids use paint for a craft, I never know what do do with the leftover paint that is still on their plate. Sometimes, I cover it up and stick it in the fridge. Other times, I try to put it into a sealed container, and then there are times when there's such a small amount left that it gets tossed into the trash. I recently found a new idea to use up the leftover paint: a Paper Plate Fish Craft!
