One flag is good and plenty. Maybe a pretty flag bunting or banner on a deck rail if you want to go all out. The rest of your items can be red, white, and blue, but try to create a patriotic look that isn't so literal. Not every piece of fabric needs a flag or stripes or stars. In the picture above—one of my favorites—only the flag and the bunting are patriotic. (I'm ignoring the star on the end table.) The pillows are in simple blues and naturals. The quilts are red and white star patterns, but they don't scream "Look at me, I'm Paul Revere!" The use of quilts, by the way, is brilliant. For all we know, underneath those quilts are seat cushions in a green and gold tropical print fabric.
