I ordered these 100% cotton sheets in pastel colors...blue, aqua, green, yellow, lavender.  They are good quality which makes the thread count seems like it's higher than 300.  I am not a fan of any fiber but cotton in bed sheets so I expect  these will age gracefully with no pilling, softening as they are laundered again and again, and become favorites because they are crisp, clean, soft cotton and cool not sweaty.
