Project indecision

I have a skein of wonderful sock yarn in my hands in Hazelnut. I'm completely undecided about a suitable pattern. I've been through all my sock patterns and looked on the internet. I'd like something organic, woody. Does that sound strange? Maybe a leaf pattern? Any suggestions? My other option is to begin a different project as I've got 2 more skeins winging their way to me through the post office. Rosie's has kindly mailed some laceweight in sky blue that I can't wait to see. It should arrive today or tomorrow!
