Living Room inspiration

I'm working on finishing my living room at the moment and I've been hunting down inspiration {aka stalking Pinterest}.  Right now the room has a hide rug that I love, 2 neutral linen chairs, a neutral couch, lamps, and end tables.  Soon to be additions: a piano (family heirloom), new pillow covers, drapes, and artwork. I love elements of each of these rooms and basically want the room to feel both stylish and cozy. I tend to be too matchy matchy and I'm trying to break that habit.

I love this fabric for a lumbar pillow....

inspired by the fabric in this Tobi Fairley kitchen...it sort of speaks to me...

but I'm stuck here.  I thought I had decided on coordinating fabrics but I'm second guessing myself.  I hope I can pull something together, I keep changing my mind and I'm struggling!
