I baked cookies one year, and individually wrapped them with a little piece of paper with something I love about Ian. He took one with his lunch every day until they were gone and really liked reading the little slip of paper.
One year I started making a scrapbook and left blank pages to add to later.
I usually make him a CD with all kinds of songs on there that he'll like.
A good old fashioned love letter might do it, depending on if Lee is the kind of guy who would appreciate something like this.
We don't usually do much and we do our best to avoid buying gifts. Generally, we just make a little something homemade and either cook/go out to dinner and split a bottle of wine. We try to avoid spending tons of time and money on V-Day, especially since it usually falls on a weekday and we're both pretty much busy 100% of the time.
