There are two camps on the bed styling front: those who hate the fuss of accent pillows and those who prefer a more put together bed. I think that a happy medium can exist between the two.
You can have a stylish bed without putting a lot of effort into it. A few accent pillows and little attention to placement go a long way. Try mixing solid colors with patterns, play with different ways of stacking pillows, or combine various sizes in similar tones. Have fun with it, they are just pillows after all!
