Anthem is tangle from CZT Jody Genovese. It was recently featured as the focus tangle on the 'Square One, Purely Zentangle' Facebook group.
Here are two classic tiles featuring Anthem.
I liked it so much I thought I'd do a whole page of it it my Book (that non-journal/non-sketchbook I've been filling recently). I did the initial drawing in black ink, and then - because it reminds me so much of crystals - I decided to add some rainbow colors.
The page is quite wrinkled, and some grays bled through from the obverse page where I'd tried something with a lot of water that didn't work as I'd hoped! (That post is here.)
