I dig this "Love Under the Stars" duvet cover featuring an illustration by Shannon Clark, "a gifted artist and photographer who enjoys experimenting with the effect color can have on one's mood," for by DENY Designs and sold by Urban Outfitters.
Totally digging this more colorful "cosmic" starscape she designed for UO, too. Also in the DENY for UO collection: Beautiful ocean pillowcases and showercurtains designed by Lisa Argyropoulos.
