Heaps of collage paper are prepared; 3-5 sheets of 80 x 60 cm cheap paper and several pages of large sketch book paper. The idea is to create masses of gestural and different marks all over these papers using brushes attached to dowls or attached to the chest. Gestural whole body movement. Big brushes, small brushes, crayons, graphite, charcoal, textas, anything really. Black acrylic paint and some mid grey, left hand, right hand. No thinking or planning.
Then you decide on a size of board/substrate and prepare these for the collage: could be 15 x 15. I chose 30x 30cm.
When the papers are finished and dry, they are cut into squares, depending on the size of the board, aiming for about 4 per board. I had dozens.
