Needing Direction

I'm redoing my breakfast room for ORC, which you can read about here.  This stripe will go on the chair seats.  This is only a partial piece of the fabric.  I ordered a quarter yard to check color.  The actual fabric is symmetrical and will be placed symmetrically on the chairs.  I just have to decide whether to go horizontal or vertical.  You can see one of the chairs I'll be using below.  I need some direction here -- pun intended -- please tell me what you think!  Both directions are represented in the photos below.
