Still playing, this time with "glazing".
Paint bands of color, let them dry.
Paint new bands of color, let them dry.
Paint newer bands of color, let them dry.
Keep going until it feels done.
(Not sure this one is.)
Sometimes let wet bands of color
run into other wet bands of color.
Have your paper taped down to a board.
Paint holding the board with one hand & brush with the other,
tilting the board to let the paint roll around.
With each new layer, your colors become so vivid.
And that makes it worth the wait!
