Yeah, I have tiny hands, too, and they've only gotten tinier since PB. My wedding band is a 6, and it's held on by the size 5.5 engagement ring that's loose except on the hottest days of the summer. On me, they appear to take up that entire first joint of the ring finger, but that's because I have freakishly knobbly, knuckly hands (I look like I have arthritis in all my finger joints even though I don't.)
Speaking of hands, does any one else wear rings as spacers because of bent fingers? My pinkies are both curved worse than boomerangs, and if I don't wear rings on both hands, my pinky fingertips rest on top of my ring fingers. It actually looks like I dislocated them both at the outermost joint by 30/45* as a child and it just didn't heal right.
