Last night I managed to make a tile with the required Quandary and Fengle tangles. It took several practice sheet to get the hang of these tangles as they are both new to me. I managed to find a good video of Quandary and that made all the difference.
I have been playing around with black, grey and brown paper for my ZIA so I did another one a little more random using grey paper and accenting with a white pencil crayon.
It looks better in person as the white highlights stand out more. Hope you like them!
