We inherited these blue plaid couches when we moved in to our new place. At first I was stumped on how I could possibly make them work with my style. But with a little (ok a lot) of time on Pinterest and some advice from my favorite decorator (my sister) I think I made the couches work.
I stuck with blue, white, and gold color scheme. I think finding a painting with all the colors, in a modern style, really helped pull things together. I also tried to vary the texture in the room as much as possible by adding a fur blanket, marble coffee table, etc. It isn't my dream home, but we enjoy it.
