We've never done much with Valentine's Day as a couple (especially now that we have an anniversary so close - now we can go out ahead of time and avoid the restaurant crowds!), but I've always loved Valentine's Day and treated it more like a friendship holiday. My mom still gives us little gifts, and I still like baking treats and handing out cards to friends like I did in elementary school. These days I make and mail cards; it's a perfect excuse to send a little note to friends and family.
Last year, inspired by these cards, I made Valentines using doilies as stencils.
You can make a variety of designs by using the whole doily or picking out pretty details. I also decorated a few of the envelopes.
And here's an idea for a different card, cutting up and using parts of the leftover doilies (of which I had a bunch after this project - so I might have this year's card design!); these envelopes are also pretty.
