I don't think I've made full bodied figures in a while, but today I made 3. It wasn't intentional, but the figure in the middle had legs which seemed to have roller skates on its feet. I went ahead and gave the other 2 figures roller skates as well and there the theme was decided. I just needed to give them a simple stage. I've been to a roller disco maybe just once in my life, but mostly I've imagined what it would be like as my first junior high home room teacher when I came to the US was a roller skating aficionado and she always dressed in loud bright color fashion. I never quite knew where my characters fit in best, but maybe it was roller disco all along.
