I almost forgot! I did a new tangle pattern for you a while back, and kept it for today. It's very like Rick's Paradox. In fact, I'll call it a tangleation.
But the difference is that it's off-kilter. You deliberately draw each round a little bit to the side. Or a lot! You can change the direction of the corner lines or round off one or more sides. It makes for a surprisinly floral pattern. Enjoy!
