I'm still really liking the pom poms! I hung them above our kitchen table last year and will probably do again this year.
Here is our centerpiece from last year -- a little Valentine's take-out box filled with candies on top of a sweet little white plate filled with candies.
Some treat bags we made for the preschool teachers. We melted chocolates in heart molds and just wrapped in plastic wrap, added a ribbon and a homemade tag.
Here's another cupcake I did. Very easy to just decorate with a conversation heart.
