Technique To Lift Wet Paint
It’s a sponge, Bob.
In the band of green in the middle-ground I used a wrung out natural sea-sponge.
Natural sponges will lighten a watercolor wash in a little more dispersed and textured manner.
Light texture will be more pronounced if color is lifted as the wash is getting drier.
You CAN scrub your paper with a natural sponge, just watch out for paper damage.
Synthetic cellulose sponges abound in my studio. They can blot large areas (and your brushes) quickly and can be cut into any shape you need.
