Oh, the things I do when I wake up in the middle of the night. Fully alert and unable to get back to sleep for a couple of hours.
I just drew a pattern of curves and arches on the page of grey-ish pastel paper and started to fill the sections in with various patterns, zentangle and otherwise. I’ve used chalk pastel pencils to add colour and shading to some areas.
A total work in progress, for no other reason than because I couldn’t sleep.
