So I took the two basic patterns and did a little tangling on top. It's really fun - obviously endless possibilities. You can see I was using a dotted paper from a pre-dotted "Moleskin" journal. The paper quality is not great so my added watercolor made it buckle. But it's great for learning the knot patterns.
Next I'll try a few with a more refined hand and good paper.
