Painting a Flat watercolor wash
Repeat as necessary…
Refill brush and continue overlapping strokes, riding the flow of the paint and keeping an even tone as you go.
TIP 3: You can use the flat edge of a wash brush to “cut” the starting edge.
TIP 4: If you want to square up the final edge of the stroke—slow down, pull the brush up, and use the sharp flat edge again. Pull it up to your line and “cut” the final edge with a downward pull.
TIP 5: If your stroke breaks up, load your brush and repeat the stroke IMMEDIATELY. See (Tip 7) below!
