This is an interesting technique that I learned recently. It's done by rubbing graphite all over your paper and then erasing within the confines of a stencil. The tangles are then done with a pen as usual. I have a brass stencil that has pens, a pencil and a brush. Only three shapes fit on my tile but that is fine by me. As I picked my tangles I tried to choose ones that would add extra black areas in it. Fun, fun! It's not a traditional zentangle but I really enjoyed playing with it.
This piece is much bigger than a tile. It uses the big butterfly from one brass stencil, the small butterfly from another stencil and the word from a third. If you look at this one closely you will see that I decided to use a pencil for the tangles on the little butterfly so that there would be even less emphasis on it,
