Thank you lovely tangler friends for encouraging me to just "let it happen". This one really just took a life of its own. I started on a piece of blue paper, and it just... grew. Brush ink pen, markers, colored pencils, lots and lots of shading over blue cardstock paper. It's super fun to work with a limited color palette, removes much of the thinking.
The tangles I can think of: Printemps, Narwal and Archer.
