If I remember correctly, this idea came to me when I was half asleep one morning. I'm really happy I remembered it! Once I drew it, it resembled "those frisbee knife things ninjas throw", as I said to my daughter to see if she knew what they were called. She didn't. I consulted the Oracle (my husband's name for the internet) and learned that 'ninja stars' is just fine, although the Japanese name is 'shuriken'. Learn something new every day.
Here's the tangle:
The black areas could fill with thin stripes for a less bold pattern. An aura could go inside the 'squares' and other tangles could be put inside that. (Yincut? Tipple?) I'll have to try some of those variations!
