This is my most recent Zentangle drawing for our ongoing WCANH Journal Challenge. The string in this book (the challenge) is the shape of a fish.
I've included a few tangles from the book I'm working on. Don't you love the Japanese waves in the background? And the tail is based on a pattern by Karenann Young, called Hairy.
I think I will put this fish in the book too, maybe in the section on shading. I actually remembered to scan the drawing before I shaded it. That's the sort of thing I always think of afterwards! (I'd love to do a coloring book).
