However... the chevrons didn't turn the corners the way I wanted them to, so I ripped out the white border and made it wider. With this wider border, two corners of the pieced border came out correctly, and two didn't. At that point I wasn't going to do that white border a third time! I decided two paired corners was a design element and it was my quilt anyway.
It's amazing sometimes the gyrations I go through to get the current project to match up with what I see in my mind's eye.
