Hi, Liz, a few questions to help with suggestions:

Budget?

Any material preferences?

What else is in the room/rooms open to this (if any)? Hint: more pics would help. :)

Are any other rugs in view of this room?

Do you want to add more color, or prefer monochromatic?

.

This came to mind when I saw your photo, but I don’t know more context to be sure ….

The mock-up skewed the scale of the pattern a bit, but gives an idea.

Hi! Thanks so much!… No other rugs in view, preferably something more monochromatic and <$500, no material preferences
