African Artist is the challenge tangle this week. It's the one all around the border. As I was working with it I was thinking about all the other tangles that start out in the same way - with curvy lines. So I pulled all the similar tangles out of my files and put as many as I could into this tile. I could only fit 7 into this tile so I drew an entire sheet with all the ones I found. I'm sure there are more out there that I haven't included - if there is one you know of that I should include please let me know!
It's amazing that so many tangles can start out in the same way but still look so different.
