When I received these sheets, I thought they seemed a little thin and fragile - but after several washes and weeks of use, I can say that these sheets are not only durable, but a pleasure to sleep on. They feel light yet cozy, just perfect for early spring when the flannel sheets are put away yet a bit of warmth is still necessary. Unlike some cotton sheet sets with a cooler hand, I don't have to curl up and wait for the bed to warm up on a chilly night. I'm sincerely glad I took a chance on these.
