This started with practicing a knotwork pattern from Celtic Art: The Methods of Construction, and ended up as an exercise in how long I could add stuff before I got bored. Thirteen hours. Not bad.
Not in a row, of course.
Oh and I threw in a couple tangle elements from The Tangles of Kells.
I might be ready to try drawing things on purpose again. Usually it’s just that my hands get itchy when I see blank space.
