I love these sheets. The description mentions "fine linen," which is technically inaccurate -- but they do FEEL like fine linen. The weave is so tight the sheets feel crisp just like back in the day when sheets were put out on a clothes line and I love that! If you don't want wrinkles, don't let the sheets sit in the dryer. They need to be taken out of the dryer promptly and folded to prevent wrinkes.
