Everybody loves these blankets. Couch throw or super comforting blanket on top of bed covers. My wife selected the first. Now we own 4 or 5. Wife, son, couch, gifts to niece and father. Easy to wash; comes out new again. Doesn't feel cheap or low quality textile like. Feels great light-medium weight! Not too hot. Not too thin or light. Just might be the goldilocks blanket.
