I love these sheets. The quality of the fabric is excellent make sure to wash and dry them before you use them and be prepared to empty your lint trap on the dryer two to three times the first wash. Some people think that the fact that so much lint comes off that it is a poor quality fabric. This is simply not true. It is the way flannel is woven, I sew and and weave so I do have knowledge of fabric and understand the weft and weave and how that creates a fabric, I wouldn’t say it was great fabric if it wasn’t. I have washed my set eight times now, they get even softer with each wash. Don’t use a liquid fabric softener, it puts a film on the fabric and hinders the benefits from the fabric. They are a fairly heavyweight flannel, it is so cozy and cuddly. I sleep hot and I just use these and a lightweight blanket if needed, pretty good for northern Wisconsin. With neuropathy and fibromyalgia fabric is critical for me and I haven’t used any other sheet set since these arrived.
