I think these flannel sheets will work for my mild winters.  They are not too thick or too thin.  I also like the color. I ordered a set of the extra long twin size for my niece who just went off to college.  My sister and I could not find them anywhere!  So when I saw them here I had to get them.  They are perfect, so glad I was able to get them.  They arrived the day before she left.  I got my self a set too.  Unless you need the super-duper thick sheets get these.  I don't know how they will hold up, but if they don't, I'll revise my review!
