It all started with a giant bouncy ball, plaster fabric stuff, newspaper, glue, cheap yarn and gobs of hot glue
Then I worked up some yarn hair.

Look at those huge neon knitting needles!

We're not sure if the hair will make it for Halloween night, it kind of bugs her a little. The ball is surprisingly light and pretty flexible considering the plaster. I wish I had some daytime photos of it in action but these will have to do!
