Noom is a new tangle pattern that was introduced last November. You can find the instructions by clicking here. It isn't had to do but really gives a neat illusion when completed. I've been playing with it in it's basic form and then adding curves and color.
The first zendala is very simple. I origionally thought of adding all sorts of additional tangles but then stopped and decided I liked it just as it was. On the second tile I wanted to add color so I got out some colored pens and colored pencils and just went nuts. It was fun
