I changed out the shams, quilt, accent pillow and duvet to a much warmer color. It doesn't have to be expensive either. I got this duvet cover at TJ Maxx on clearance for $25. The quilt and shams were Christmas gifts last year from my parents but I have seen similar ones at TJ, Target and even Walmart. I already had the accent pillow. The key is to not have to change everything. I just chose a few key pieces and got a whole new look.
