Take an old OP, and see how it can be reimagined. Just playing. Did this OP early in my Wetcanvas days when I had just discovered oil pastels. Images from then
Those days really made a difference, all the artists, you especially, gave me a sense that it was worth just one more try. So many good memories. I even laugh at my follies when trying to use OPs. And make them do what I wanted! That didn't go well.
