Hey, I want to suggest new canvas shape idea.
image of the shape:
funnel?
Think that’s what he is going for
it appears to be a tube with no thickness, which imo would be a lot nicer to use than current tubes for stuff like curved walls (assuming you can hide the fact that the wall is paper-thin, anyway). Kinda hard to tell with the angle though
i’m pretty sure it’s just a lampshade type shape
