Cute soft and cuddly
So soft, cute and cuddly. The quality of softness and materials used are amazing. It’s light weight and fluffy but not thin. The size is perfect for cuddling. Not small sized. Gifted this to my mother for her birthday. She loves it says it’s so soft on her skin. Don’t imagine I would have an issue with washing or drying. Price was awesome and definitely would purchase again.
