I think that with your 'gold' 4-patches being essentially the same color as your 'gray' HSTs, you will not see the 'gold' 4-patch grid running across and vertically through the pattern that connects the star blocks and surrounds the alternate block, and which depends on the gold-gray contrast. I just point this out so you will not be disappointed after you've done all the work!
