I got bored with the old layout in the room and rearranged it a bit.
I put the sofa where the chair was, changed the angle of the rug, moved the lamps around a bit, put the door from the small side table to the tall side table, and got a new pillow to put in the chair. Nothing much, but the effect is much more airy.
View from the door.

I also shortened the curtains, but that was more because of the cats pulling on them. Now I like them more than when they were long, and the double thickness provides more privacy, so it's even better than before.
