Everything that goes on the bed, in one order, in the same cloth.A fitted sheet with a 15 inch pocket, a flat sheet cut generously enough that it still tucks after it shrinks, and two pillowcases. Twin ships with one case, since a twin bed takes one pillow.Sateen is a four-over-one float, so four of every five threads sit on the surface rather than being tied down into the weave. That is where the low sheen and the cool slide come from, and because it is structural rather than a finish, it survives washing. The count is 300, near the top of what a square inch of cotton will hold before the yarn has to be thinned to fit. The cotton is long-staple, so the yarn spins fine and even without the short ends that make cheaper cotton pill.Buying the set matters more than it sounds, because sheets bought separately over a few years rarely match once each has faded on its own schedule.The color is the cotton's own. No bleaching and no optical brighteners, so it reads as a warm natural off-white rather than the blue-white of most bedding.Cut and sewn in New Jersey. The sateen carries Global Organic Textile Standard (GOTS) certification under license GOTS-10229, issued by Oregon Tilth, and the license number is public so you can check it yourself.
