Question: Valentine ideas

I don't normally do much to celebrate holidays. It always has a way of creeping up on me unexpectedly. But my children love any small effort I take to make a day special.

I'm looking for simple Valentines ideas. They can be projects, food, crafts, whatever. I don't want to invest a ton of time and like to use things that I have in the house so I don't have to go shopping!

I know some of your are super creative AND frugal. What have you done to make Valentines Day special for your little ones (or big ones)!
