I had a pair of old shoes that didn't work anymore so I decided to paint them white and draw on them. I painted them with acrylic since that's all I had. I didn't really draw on them for any other reason than it was something to do with them  but it it was useful practicing more with sharpies and making use of their 'draw on anything' quality by working on a different kind of surface. I once again didn't give the figures faces for no other reason than at the moment I like how that looks.
