I did this oil pastel sketch on the first day of the life drawing workshop. Each pose by the model was for 5 mins. The model would go into another pose for the next 5 mins and so on until she had done six different poses. I started in the centre of my paper with my lightest yellow oil pastel. The drawings were layered on top of previous sketches using stronger coloured oil pastels as I progressed. This was a real fun exercise.
