I don't have a Valentine, but I like the idea of the day. Although, whoever is loving you should be loving you all day, everyday. Here are some Valentine's cards I made that was going to sell but didn't get around to it this year. Hopefully next year I'll have a fully fledged online business at least and you'll be able to buy them.
I hope you all have a lovely day and if you don't have a Valentine, don't worry. We singletons shall unite!
