Bedding
Treat yourself to new bedding from essential sheet sets to textured quilts with matching shams. Since bedding sets are something you change regularly, restocking your linen closet on a regular basis makes a lot of sense. This is one of those upgrades that feels like a luxury, but it really is a necessity. Try linen sheets to keep comfortably cool in summer or layer a duvet cover over sheets and pile on a quilt in the winter--it can also act as a coverlet. If you indulge in a new bed, it's a great time to buy new bedding, too.
