A tessellated tangle - SELEST!
Here is a tessellation - an arrangement of shapes closely fitted together, in a repeated pattern without gaps or overlapping, inspired by an Islamic pattern. The name of the tangle - SELEST, is an anagram of the first part of the word "tessel"ation :)
The step outs show ways to use the tangle as a plain background or a monotangle. Once you draw an additional aura inside it, it can be used as a string to fill it with other tangles or just fill it in with black.
Lots of possibilities of light and dark! Hope you enjoy using it as much as I had fun deconstructing it!
