Pocket Geometry

I've been having an interesing time trying to figure out the pockets
on these shorts. I'm using a bound button hole technique in a large
scale which creates some great lines and strong joins. The pattern of
the fabric is vertical stripes and I wanted to keep the lines going in
the same direction for the pocket facing. I struggled with this for a
few minutes before realizing this was the moment my high school maths
would pay for itself. A 45' angled pocket hole would allow for the
fabric to be laid on the horizontal and folded up to match the
vertical lines. Geometry in action!
