You'd think that once you got past the December holidays, it would be possible to skate by for a while without having to craft any themed decorations. You would be wrong. For DIY bloggers and people who actually get enthusiastic about vaguely pagan cultural holidays (like Halloween), Valentine's Day is a reason to deck the halls with red, white, pink, hearts, and chocolate.
What does S. Valentine have to do with hearts and cupid wings? About as much as S. Patrick has to do with green beer. Some sources say that Valentine's day is a holiday commemorating the martyrdom of S. Valentine; others say that it is the Christianization of a Roman pagan holiday that celebrated fertility. In either case, written Valentines showed up in the 1400's, and it became a popular holiday celebrated by the common folk in the 1700's. So, all of you who will be enjoying boxes of chocolate on February 14th have a Christian martyr (possibly) or a Roman pagan fertility holiday (possibly) to thank for your candy.
Knowing a smidgen about the origins of Valentine's Day should make you feel better if you don't happen to "have a Valentine". There is no reason to hang your head and cry, nor to rush to your nearest bar to find someone to be your Valentine, unless you are really jazzed up to celebrate the memory of the murder of S. Valentine, or alternately the Roman festival of Lupercalia.
I realize that I am supposed to be writing about recycled V-day decor projects right now, and that I totally just launched off on a tangent. I really just need you to know, from the bottom of my heart, that you are OK the way you are. You are not a loser if you are single and have no Valentine. You are great; you are loveable; at the right time, you will meet your husband, wife, life partner, electrician, plumber, butcher, baker, or candlestick maker. Who cares if your coworker gets a giant bouquet of flowers from her gentleman caller delivered to her desk? One day they will be miserable together, and they will break up, and she will come into the office eating bags of nacho cheese flavored chips to dull the pain. If you don't want to buy into this holiday that makes so many people miserable and lonely, I personally give you permission not to.
