We have twin extra long beds, so I ordered twin x-long sheets. They either shrank in the wash or they sent us just plain twin, because the flat sheet just barely has enough material to tuck into the bottom. The material was beautiful at first, but lost it's sheen once they were washed. And, of course, they wrinkle, which I expected. They are rather thin, being only 300 TC. I should have ordered some that were 400 or 500. But in spite of all this I like the sheets, and I'm going to keep using them, especially in the winter. Because, believe it or not, they are warm.
