Valentine's Eve Dinner Party

I have "hostess-itis"... meaning I love, love, LOVE being the hostess. There's nothing like planning and throwing a fun party. So I decided to host a Valentine's Eve dinner party for a few close friends on Friday, February 13th. Serg kinda gave me a sideways glace when I mentioned it but seemed to quickly warm up to the idea.

Well since I sent out the evites, I've been thinking about how I'm going to decorate. HomeGoods has been emptied of all cute Valentine's decor and Target's hasn't been that great. I settled for purchasing a white tablecloth with the idea of dressing it up with a runner and lots of great flowers. But... I don't know how to sew (yet!) and I'm not so good with flowers (they die the minute I touch them, or at least it feels that way). What should I do?

I've been scouring the internet and this is what I've liked so far...
