Kisses, chocolates, flowers, or railing against it as a commercial conspiracy, no matter how you spend it, have a good one. We stuck to our £5 limit and exchanged a fancy coffee mug (Jules to me), cards (all around) and homemade gingerbread love hearts (me to Jules).
This image from Martha Stewart is a little Valentine project I actually attempted one year, translucent waxed-paper hearts, which I hung in a bright-but-not-sunny window of my old apartment in Rogers Park. Even though I was on my own for Valentine's that year, I'm still a sucker for hearts and chocolates, and didn't see any reason not to celebrate on my own.
For those sourpusses who disagree with me, here's a special Valentine video from Misery Bear. Enjoy.
