"Abbie's Room."
Okay, since my name is Karen, I'll explain. It had always been "Mom's sewing/junk/stash/if-we-don't-know-where-to-put-it-we-throw-it-in-there room." Then I took over my firstborn's upstairs bedroom after she moved out. I tried to christen it "the Second Story Studio." I even thought of painting a sign for the door. Somehow that never stuck. I usually find myself referring to it as "Abbie's Room," and probably always will.
Of course, about mid-November it became "Santa's Workshop Southern Auxiliary." Come December 26, it will just be Abbie's Room again.
