I made this runner as a piano scarf for a friend, sort of based on a pattern I downloaded. But the binding directions are the generic directions for a regular 90 degree corner. How do you make a neat turn at the pointed end?

I probably can figure out the slight angle where the taper begins, but how do you turn at the pointy end? I searched the board but didn't find anything. Help???

Picture is kind of weird. This thing is 8.5" wide by 57" long!
