Percale or sateen?

All three are good choices. The difference is in the feel and in how the fabric behaves during the night.

Percale: crisp and cool

In a plain weave the yarn passes alternately over and under one thread. The surface is matte and feels cool, like a well-ironed shirt. It suits you if you sleep hot or like hotel sheets.

Sateen: smooth and warm

In a sateen weave the yarn passes over four threads, so more yarn sits on the surface. That is why sateen is smooth, has a slight sheen and feels warm. A good choice for a cool bedroom.

Washed linen: relaxed and textured

Linen breathes best. It moves moisture away from the skin and evens out temperature in both directions. The stone-washed surface is soft and creased, and it doesn't need ironing.

In short

If you sleep hot, choose percale or linen. If you feel the cold, choose sateen or linen. If you hate ironing, choose linen.
