First of all, you aren't clueless :) I would follow your gut and turn the couch to face the fireplace, put the TV on the oak box near the window, the armchair and side table over near the built in dresser, and the red cabinet between the two windows where the armchair was. I like both your pieces of art on the other side of the room. If the red cabinet is between the two windows, you might want to switch the vertical piece with the one that is on the wall above the dining table - just see how it looks. Actually, I think the bird painting could look really good above the fireplace - it will add visual height (as jonathan suggested) and brings some red to that side of the room and it has bits of black and charcoal to tie in the fireplace and the couch...... If you have the TV to the left of the fireplace, I'd move the map (I like it for personal reasons :). Anyway, you really want a mirror up there.... it's a bit tricky because the fireplace is off set. Something this shape would be fab because most other items in there are really angular, but this one is too big and the price is crazy: Otherwise maybe a couple of small mirrors that you can also off set and put in a group, which would also add height: I'd do three or five of different sizes and shapes. I actually like the rug size and colour - it ties in with the blinds and the taupe in two pieces of your art and has good texture. Add a few more cushions to the couch and armchair in a couple of different fabrics. Maybe some of these:

Hi Pannacotta, I think the etsy one may be unique rug store, they overdye vintage rugs. I really like the rug from westelm, will it be too modern though if you didn't like the JL striped one? What do you think of their Cadiz one? I can't decide if I like it! Try both of these links from ebay, you may like a couple, they're over budget if you go for the new size but under if you go for 2x3 http://stores.ebay.co.uk/rugmartoutlet/_i.html?_nkw=Faded+vintage+retro&rt=nc&_pgn=1&_ipg=48 http://stores.ebay.co.uk/rugmartoutlet/Modern-Patchwork-Rugs-/_i.html?_fsub=7903057012

Can't find the same rug available here but there's some similar colour/sizes ones available on overstock. I've bought a large rug from them before and thought the shipping costs was reasonable and arrived quickly. http://www.overstock.com/Home-Garden/nuLOOM-Distressed-Abstract-Vintage-Oriental-Multi-Rug-710-x-11/10809306/product.html?recset=19a59283-7959-4d3a-adb7-f7c93de16945&refccid=XZPXEP6ZWXW22X2MEGIKU2DPTM&recalg=828%2c512&recidx=3 http://www.overstock.com/Home-Garden/nuLOOM-Southwestern-Flatweave-Wool-Multi-Rug-76-x-96/10082382/product.html?refccid=HFG5ZRPQYVO32YSAJG73CLFCCY&searchidx=58 http://www.overstock.com/Home-Garden/nuLOOM-Contemporary-Hand-tufted-Wool-Moroccan-Triangle-Beige-Rug-7-6-x-9-6/8282920/product.html?refccid=YTECKEYTYR6J5DCLQSGULDOIO4&searchidx=146 Other nice options: http://www.urbanoutfitters.com/uk/catalog/productdetail.jsp?id=5532436280007&category=RUGS-EU http://www.westelm.co.uk/margot-selby-zigzag-stripe-kilim-rug-t2461 http://www.westelm.co.uk/palmette-chenille-wool-kilim-rug-midnight-t2467

Not all of our murals are photographic, Lauren. We have some grisaille style ones too! :) We have a huge range of murals from collaborations we've done with artists from around the world. So maybe there'll be something for your taste there. Please feel free to roam around our website if you are looking for a mural. Our design team are also on hand to answer any questions :) Nicole from Wallsauce
