This is step one for an undersea painting I started a few weeks ago. I wet the paper on both sides and while it was really wet I started adding the colors. Then I added various items to make textures; torn wax paper, coffee filters, rice papers, and gauze for the stringy stuff. This is my favorite way to make an under painting or background. I planned ahead that it would have turtles, fish, coral, shells and rocks. I have used salt for texture, too but I'm getting away from that because I've been told that it will attract moisture, especially in our FL humidity.
I have another picture of it as it has progressed and will post that tomorrow.
