I think I'd maybe go with a stripe in varying shades of whatever colors you are using. I see those in a lot of cottage style homes. Or if you are doing a more "cottage by the sea" look, anything beachy. I think the roses would also look wonderful in a cottage setting if you want a soft romantic look. Luvs is right though, without knowing your decorating preferences it's hard to give a suggestion. Good luck! ~Anj
