I did another Celtic Knot! This one is loosely inspired by an M. C. Escher woodcut, (shown below), which happened to be the last design he did before he died.
I get all that from a big book of M. C. Escher’s artwork I’ve got called Impossible Worlds: https://www.goodreads.com/book/show/998629.Impossible_Worlds
You can see that I didn’t finish my work to quite as many iterations of infinity as Escher, and it doesn’t have quite the level of craftsmanship, but still I’m always pretty happy when I finish another knot!
