YES, this is the design for number 6 flipped 180°. I'm allowed to do that because, despite the protestations of fans of the number 9, that's all it is.
Besides, I didn't just flip it. Well, the lines I did just flip, but that's not the whole story.
I actually had to redo the shading and colours, so there is definitely more to it , honest. What do you reckon?
