Think fluid, think of how the colors flow one into another. Notice the textures, rough water and tranquility. Notice how the sunlight glints off the surface or how it gets lost in the white water. Even notice how the fish jump and the frogs and bugs interact with each other in this unique environment.
After you’ve got all that down, grab your needles and head on over to Jane Thornley’s site (remember, she knitted a beach, and a forest?)
