Straps on ladies sandals have a mind of their own. I am moderately satisfies with them at the moment but may change the angles slightly as I paint them. There is a little more detail to go in the background of the top row, particularly on the left, but that can wait until just before I paint. When I use a soft pencil to outline the composition the paper can become a little 'grubby' but I erase this before I apply the paint. On this photograph there is a shadow from the studio window frame.
