Needle felting on polystyrene/styrofoam

 I was searching online for inspiration for making more needle felt Christmas ornaments when I came across a tutorial for making these baubles.  They are covered styrofoam balls.  I was unaware that you could needle felt into this medium!  The tutorial for these baubles can be found here it is a lovely site with many ideas.

I had no sytrofoam ball's to hand, so found a piece of polystyrene that had come in the form of packaging and had a go at needle felting it.  As I was just having a practice to see how the two medium's worked together I did an abstract pattern.  In all honesty I was just doodling with wool! This was the result.
