Wrapping tepee cover

[Magnus Forsberg]

A canvas tend to be flat...

I don't understand this.
It is always possible to roll a flat sheet, of any shape, into a perfect cone. I don't see why it has to look like this. I'd expect the top corner to follow the yellow arrow, and not extend in a tangential direction. Is the canvas very stiff, and don't want to be rolled up?

And maybe that corner is a tiny bit to long? If I look at pictures of a flattened canvas, it looks to be symmetrical.
