Using a charcoal, crayon or pencil document in sweeping gestures any ideas that come to mind. Try using the side of your tool, as well as your non hand to what you usually use yo allow more freedom and exploration within your gestures.

Using colour (pen, texta, or copic marker, paint etc) begin documenting in shapes all ideas that come to mind. Use different ends of of your marker pen to explore shapes in both 2D and 3D. Layer and build your shapes.

Using any paper, cloth or cardboard that you have available begin creating forms. Don't overthink the outcomes of the forms, use your hands to sculpt and shape the material.
