Fall is officially my favorite time of the year. As a Pacific Northwesterner, born and raised, the air turns crisp, the rainy season has not quite arrived, and the occasional evening of an outdoor fire with smore's always makes the kid's happy!
I lean toward simple decor and don't change things too much from a seasonal standpoint, but when you do, simple changes in pillow covers, table linens, curtains, and foliage seem to do the trick. Not to mention pulling out the pumpkin spice candles! I can never get enough of those!
This living room design is a great place to start. Just add pillows, blankets, and other decor with a seasonal color scheme that you LOVE!
