Well, okay...I don't have a white pen or black paper...yet! So I am going to cheat a little and ask everyone to pretend and reverse my blacks and whites! I am also posting some more of past challenges on my zentangle display sidebar. This one I am showing is Starry eyed...challenge #4.
And I am posting the "prototype" for my center design. This is a picture from Nat'l Geographic...it is some kind of underwater plant, I think...but I thought it was a cool shape with neat texture.
