Your room is so neutral, it is hard to know where to start with colors. Because of that- I thought I'd show you two totally different options. The first is the more neutral of the two.
The Chrysanthemum rug is from Martha Stewart's line on homedecorator.com.
The pillow is from DwellStudio- I would get a couple of these as well as some solid blue and brown throw pillows.
The drapes are from West Elm. I would get three panels.
Next- I wanted to show you a more colorful option:
The rug is from homedecorator.com.
The bird pillow is from DwellStudio. I would also add some solid color throw pillows to the mix.
The drapery panels are from Pottery Barn.
There you go- let's all vote for Laura- which collection would you go with? They are both very similar in price- The colorful options total $569 and the the neutral items total $537.
