When I got them I was really excited because they felt like some of the softest, silkiest sheets I've ever owned. I washed them exactly per the directions (wash cold delicate, dry delicate low heat) and dried the fitted sheet separately from the flat sheet to reduce wrinkling. They wrinkled more than any other sheets I've ever owned, especially the pillow cases. And the fitted sheet is about 1-2" shorter than it needs to be - really have to stretch to get it on. I gave it two stars because the flat sheet is plenty long enough to easily tuck under the foot of the bed, unlike the last cal king set I bought from Overstock. They are average thickness, maybe a bit on the thicker side. Haven't had good luck with sheets here, might be the last time I purchase sheets from the Big O.
