I saw this set of Yo Gabba Gabba nesting dolls on Gabba Friends a while back, and decided to attempt a set for V. I picked up the blank dolls at Hobby Lobby for about 6 bucks. Mine are decorated with acrylic paint and permanent markers.
They're not perfect, but V loves them. :) They were actually supposed to be for Christmas, but I caved, and gave them to her early.
If I were more artistic, I would attempt a Mario themed set for L, (Luigi, Princess, Mario, Toad, and a mushroom.)
