Today's Mathtober prompt is "Faithful", which apparently means "equal" in mathematics. I had to look it up. So, I'm going with two sets of fish for today's #inkyDays drawing.

I also finally finished a big piece that I've been working on for the last few months. Feels fantastic to finish it at last!
