For quite a while I had several blank sheets of paper tacked to my studio wall as I worked on other projects. After a while their perfect empty whiteness kept me from approaching them at all, so one day I grabbed a brush and a can of enamel (it was handy) and painted a figure on each page.
Now they weren’t perfect. Now they had to be fixed. I could work with that.
So I turned them all upside down and tacked them back up on the wall, and made these drawings on top of them.
