After an absurd amount of deliberation and playing around on JA's "Design Your Own" site, here's the pattern/colorway I'm going for (you can reverse these rugs, thus the two samples):
So ready to move this sisal one to a different room...probably going to the guest bedroom since it will work nicely with the color palette in there.
It will be 11x13' so the chairs will no longer have to cling on to the edges of the too-small rug that's been in there thus far...
Apparently it takes foooorever to get a JA custom rug...I've been warned to be super patient. Apparently each rug is hand-loomed by Peruvian artisans. If I can wait 5 months for RH dining chairs, I suppose I can handle a long lead time on this too.
Let the waiting game begin :)
