You may have already seen this over on CRAFT's site, but just in case you didn't, I designed a crochet pattern for them ... this cute crochet heart scarf.  

I know I'm not giving you much lead time if you want to make one for V-day, but it's a quick crochet, so you could make one tonight if you don't have anything else planned.  Grab some yarn out of your stash, put on The Princess Bride, and get stitching!
