Pat Lillich just likes to play - ever since her father gave her some scraps of wood, a hammer, nails and a bunch of springs to play with in the garage beside him. Figuring out how to make something work evolved into trying to figure out why her clay figures just didn’t look like those in the museums. Both endeavors look to be lifelong obsessions.
