Painting a Flat watercolor wash
Make your second stroke
Return to your palette and refill your brush.
Start the next stroke at the bottom of the first stroke, being sure to overlap the bead of paint now formed at the bottom of the first stroke.
TIP 1: If the flood of the first stroke doesn’t fully flow into the new stroke, increase the angle of your board to aid the flow of the wash.
TIP 2: Increasing the angle of your work also increases the chances of drips running wild down your paper. If they annoy you, work faster or keep a tissue or damp sponge in your free hand to quickly blot them away.
