I started drawing this because I'd seen some of Stephanie Pui-Mun Law's latest celtic knots and wanted to try some myself.
As you can see, I've got a lot of work ahead, if I ever want a truly cool celtic knot. These, however, are Frasur knots. They don't really tie or intertwine, but they encircle and are aspects of life.
Analyze away, or just enjoy, or don't.
