So...
1. Color. Be brave. Don't be afraid of clashing or going against your current color scheme. The more unexpected, the better!
2. Eclectic accents. The next time you are at a flea market and that strange portrait painting calls to you, or the estate sale 70's throw pillows sing to you, don't think twice, get 'em.
3. Lived-in look. Keep cozy blankets draped over chair backs. Leave a stack of your favorite poetry books on the side table. Keep a cork board by your door with colorful cards from family and friends. Keep your pretty and loved things close!
Your home will be more playful in no time!
