The theme? Use a tangle as a string and then draw a tangle inside it.
It didn't come out quite how I wanted, but that's the way it goes. I feel like some of my linework is a bit clumsy - not only haven't I really drawn much for a couple of months, I'm getting used to drawing with new glasses - my first set of multifocals - they make me feel old. haha. If you're shortsighted like me, it's such an insult to wear glasses (almost) your whole life and then have your reading vision go on you eventually too! Really not fair at all!
