Most of Pottery Barn comforters work well.

If you are willing to use duvets, the company store is a good place to look. They have a few comforter sets also.

Try Overstock.com. If you can use a duvet cover, try Crate and Barrel and West Elm. They both have a nice selection of contemporary designs.

Dark wood with blue is a wonderful combination.

Last summer we painted our master in BM Palladian Blue which I like, but it sure is blue (DH picked it-I'm more a green person-oh well). I tried a variety of bedding and ended up going back to just a clean white duvet cover on the down comforter. The draperies are from Pottery Barn and just about match the walls perfectly, but have some shimmer (dupioni silk). I like the look.

We have blue/gray walls and my bedding and drapery is in white and ivory. I love the look, but am going to add some persimmon/pumpkin accents for the fall.

The nice thing about white and cream bedding is that you can collect nice linens slowly over time that will all go together.

Great suggestions ladies, can you show me your bedrooms with the white comforters in the room?

Where do you get nice decorative Euro pillows and accent pillows?
