One thing I seem to keep coming back to on my Pinterest boards is my love of a striped rug. They warm up a wooden floor, or add interest to a neutral carpet. If you are just looking to give your room a “pick me up” it could be an inexpensive option. French Connection and Urban Outfitters have a good selection as well as good old Ikea. Do not forget TK Maxx either. Hit and miss sometimes but I have found a few Dash and Albert style rugs in there over the summer.
