Mostly I keep my shape and skin the same. Very comfortable with my avatar and it is definitely a dream/fantasy design. I've just changed skin for the first time in months as I finally found a decent tiger-neko skin. Only changes I make to my shape are whether or not I'm pregnant at the time. And I was wondering if anyone knew how to create a set of custom shapes for multiple births? I've made a nice set of normal pregnancy shapes but not sure how to alter them for multiples. Not even sure if this is the correct place to ask but it was the only discussion of shape that I could find.
