How can I create a cozy bedroom atmosphere with a floral rug?

Your floral rug in the bedroom can be accentuated by your soft furnishings. It sounds as if you have green and white as the basic colors of the rug, so you could repeat those colors in your bedding. However, green and white are not warm colors, so a contrast touch of pink or red, in plants, curtains, or a soft plush throw, would enhance the coziness of the room. You could also echo the white lilies with some cushion covers featuring a white lily pattern.
