Top section of the composition was top heavy and needed some reduction and veiling. I mixed a grey with added red green and ultramarine in very small quantities making an earth -grey that I overpainted sides and top third of the composition obscuring shapes beneath.
Later when paint dries thoroughly I plan to swipe paint on a rag across raised areas exposing faintly raised parts of shapes beneath.
At this stage too the circular shape seemed to fight for attention so I painted it over with the grey shape that leaves exposed the main part of the painting and then with a soft rag whipped back some paint leaving part of the circle showing through faintly. Also left exposed is a triangle shape reminiscent of a Mungo dune beneath which is my handwriting left uncovered through masking out noting time and place of making this frottage remnant. A few more layers needed yet. Do I see a strange creature emerging?
