September is the time of year when we start to think about the indoors more than the outdoors, what with the weather shifting and the leaves starting to turn. Getting cozy in bed is part of the allure of the Fall, in my opinion anyway. That's why I think a new duvet cover set is a great way to start the season. Here are a few that really make me feel like it's time for a change at my house too. Have some fun. Whether you find something for under $50 (try Home Sense and Ikea), or something much more extravagant, new just feels like a great way to get this year going right.
