Look up flat weave wool or solid dhurrie rugs. Many years ago Pier One carried them. I have a not so clean one in my attic you are welcome to:). You may have some luck at a local carpet store. My online search shows all patterned and ticked styles. Presently solids are not on trend it seems.

The larger rug looks much better. I would pull in the silver gray color from the desk (that's bitchin') into the rug, perhaps in an ombre look with some browns and muted orange/reds. Keep any pattern small, that desk and panel wall need to remain the stars of the room.

This is the other fabric. Btw..that plaid looks more “goldish in that pic than it really is.
