These sheets are fantastic, and I'm a linens snob. When they showed up I was impressed with the feel of them, but when I put them on the bed they were too slippery in a plastic-y kind of way; so I washed them, and OMG the difference! I was careful to wash them exactly per the instructions, because there were a lot of reviews that talked about pilling. Delicate cycle, cool water, mild soap (woolite), tumble dry low (I did use an unscented dryer sheet)... and they came out like crepe silk, NO pilling AT ALL, just luxurious silky fabulousness. They are VERY thin, which might bother some, but I take it as part of the luxury texture, knowing how strong bamboo is so I'm not worried. BTW, the "au natural" color listed for the King size is the same thing as ecru.
