I have lived in 2 log homes. I understand your problem! Do you have any interior stonework also? Last time I was in this position, I tried to pull the base color of the rug from the lightest tone in the stone on my fireplace, so that I didn't end up with too much going on. Jewel tones do seem to work well, also. I like the last 3 you posted in the comments. It is really hard to pick unless you can see the rugs in person, too. I ended up ordering my last rug through a local furniture store, where I could see and feel samples. They ended up being very competitive on price. I tried ordering online first, and the colors always seemed a little "off" once I got them rolled out in my wood-everywhere house.

Thank you so much for the feedback. I love the idea of adding the drapery. Would the room look better if I moved the couch more towards the left? It centered in the front facing picture but it looks too far to the left because of the shape of the room.

This is what i might try a square rug that is placed in the space between the stove, the counter, the yellow line i see on the floor and the wall. however, I would experiment with arranging the furniture like this Push the left half of the modular sofa into the corner. Turn the other half of the sofa so it directly faces the wood stove. Bring the pieces of the modular sofa close enough to each other that you are left with an empty square in the corner where the counter meets the wall. Arrange your tables inside that squar, and plan to put a plant in there as well. Or a two-headed floor lamp. i think i would might buy a black and white rug for that space. An indoor outdoor rug might work best.

So Sorry, But The strict rectangle rug shape on a diagonal makes NO sense unless the furniture angles with it. Looks exactly as what happened, The rug size not suited to space. WAH However, as also suggested above??Get a black and white zebra hide- ( any hide! ) play with the position !! You can even trim it. Double up and layer as you change directions! Freedom is again, the irregular shape and iconic blast of "pattern" This is 5 x 7. It's 299.00 At Wayfair . This you CAN angle and jiggle to suit your fancy! It's shape and decorative accent, allows you the freedom from "perfection"/ Matters not if a portion sneaks under a sofa and the rest doesn't. ! Matters not if a portion sneaks under the tv console!!! You can even LAYER a bold one over a more subtle, or get two the same and layer! The bonus? Spills wipe right off : ) any of them. https://www.wayfair.com/rugs/pdp/everly-quinn-khanna-animal-print-handmade-cowhide-zebra-blackoff-white-area-rug-bbmt4822.html Here's one in brown, 6 x 9 https://www.wayfair.com/rugs/pdp/world-menagerie-lahti-zebra-cowhide-beige-area-rug-wdmg2852.html Another at 6 x8 https://www.overstock.com/Home-Garden/Faux-Cowhide-Camel-Brown-Beige-Area-Rug-310-x-5/9775380/product.html?refccid=HGY5DTLFTGDLVVCNGLNNWX5D3Q&searchidx=19&kwds=&rfmt=material%3ACowhide&option=7210359 6 x 7.5 below https://www.perigold.com/rugs/pdp/saddlemans-animal-print-cowhide-blackoff-white-area-rug-sadl1095.html Great style, and so much fun : ) 6 x 8 below https://www.overstock.com/Home-Garden/One-of-A-kind-Handmade-Real-Cowhide-Rug-From-Brazil-Big/28947395/product.html?refccid=HGY5DTLFTGDLVVCNGLNNWX5D3Q&searchidx=39&kwds=&rfmt=material%3ACowhide&option=51205192 Point is have some fun with it.
