I vote basement. That's where Girl Cave is. Funny thing, when I'm down there all my boys (9, 10, DH and dog) find their way down to visit and chat. I think both boys like being able to come down and have "private chat time" with Mom! Plus, while I admit to being a relatively neat quilter, it's nice to be able to turn off the tv and sewing machine, shut off the lights and walk away!
