Waybop is one of the newest tangles from Zentangle. You can get the steps in the Zentangle newsletter from Feb 14th. I was lucky enough to learn it at the CZT get together last November. It's a fun tangle with lots of ways to add your own personal flair. Most of the artwork shown in the newsletter shows it as a central element in the design. I decided to try using it as a border. Along with Waybop I used Betweed and a Mooka like shape.
This is the linework from just the Waybop.
Finished line work before shading.
