Who said geometry isn't fun? We love the geometric patterns of the Air Blue and Chocolate Diamond Sheet Set from Serena & Lily. This sheet set, made from 230 thread count cotton sateen, is a great compliment to the Asher bedding collection. Each set includes one flat sheet, one fitted sheet (with deep–pockets) and one standard pillow case for twin and two for full and queen. Machine wash. Ships in 2–3 weeks.
