So I consulted the Zentangle newsletter and had a better look at OoF. I realized that if I oriented the little squares as diamonds it would work . Then I was away. Here's my first tile, with OoF in the top left and bottom right. I had trouble always getting the arcs to connect to the correct side of the little square, and botched a few by overshooting. That's the inspiration for the curvy fills in the lower right: trying to incorporate a few stray lines. I quite like it!
|Tangles: OOF, Crescent Moon, Hollibaugh, Seljuk and unidentified|
Here's tile number two. There are two variations on OoF in the "pendant".
|Tangles: OOF, Beadlines, Hibred, Lotus Pods|
