Use masking tape to create straight lines across the canvas in a random layout, varying the lengths and spacing​​.

Use navy and your palette knife to add paint underneath each tape line. Keep the marks organic and textured.

Mix navy with white to create a dusty blue, then add it into some of the wet navy marks.

Paint used: 703 + 116

While the paint is still wet, add small touches of white and beige into the lines so the colours mix naturally together.

Let the paint dry, then remove the tape to reveal the clean top edges.

Mix white with water, pour it over the canvas and spread it across the whole surface with your hand.

While the wash is still wet, lightly dab some of the white away from the painted lines so parts of the navy show through again.
