When I was a child I loved to go to my grandmother's house because the blankets she had were knitted...100% cotton...and heavy...I always slept so well there because of it...I continued to buy them for years and that was the only way I could sleep...They're rather cheap at Wal-Mart, etc...they are great...Not sure that the more expensive ones are needed...It's not like a comforter at all, they are much heavier, especially if you get a large one and fold...
