Triangular.
I usually don‘t use straight lines to draw the string on my tile. Here, I decided to use straight lines to make triangular areas on my tile as the basic divisions.
I also had a hard time making up my mind, which was the visual “top” of the tile when I was finished, which is why Msst is moving in an uncommon direction.
