With Valentine's Day looming in our midst, it's high time to start thinking about what you'll be cooking up and crafting for your sweetheart.

So, instead of spending your dough, fold it into a beautiful origami heart to give your loved one. Better yet—make a whole bouquet of folded dollar bill hearts. What could be sweeter than a bunch of heart flowers made of money?
