Diagonal lines on Surface

Hi Guys, 

I can't for the life of me figure this out.  I need to finish the diagonal lines on the surface below which is going to be a diagonal weave.  I can get all the lines drawn except the last half of the one direction.  All the flipping and reversing doesn't get me the last bit.  Anyone have any idea?

As shown in my definition, I'm currently Shifting the list of points by one, then using Flip Matrix.

I figured out my initial problem.  For the one that I couldn't get the other side of, I just reparamed the surface, took the side I did have, got the points UV coords on the surface, then 1-x to get the opposite and evaluated that point back onto the surface. Phew :)
