These sheets don't feel like the usual 600 thread count sheets. They're very thick and almost feel flannel-y. If you're looking for the crisp, sleek feel of high thread count sheets, these aren't the sheets you're looking for. If you're looking for sheets that feel like they'll last a really long time, these might be for you. They feel very tough and strong. They fit my (queen-size) extra-deep mattress quite well. The sheets are single-sided, in that the reverse side is unfinished and probably not as comfortable in skin contact (referring to the flat sheet). When washed and dried the sheets shrunk irregularly, making it difficult to get the pillow cases to sit right on the pillows. They also wrinkle very badly, more so than my other 100% cotton sheets. Finally, the wedgwood blue is more of a bright sky blue than the muted grey-blue of true wedgwood, and it turned out not to go well with my slate blue comforter. I think these are good sheets, just not great ones and not what I expected for 600tc.
