Soft!!!
Size: Throw(51" x 63"), Color: Light Grey
This blanket is very soft, but it’s not made the same on both sides. And it doesn’t fold easily because of that. But it is very soft and comfy. I hope it lasts after being washed cause many things lose their softness after being washed.

Soft, comfortable!
Size: Throw(51" x 63"), Color: Cream White
The softest blanket we own! Definitely seems durable and so warm, love that it doesn’t shed and the material has held up well after a couple of washes, I wasn’t sure about the price but it is our favorite now.

Luxury and priced so well.
Size: 60''x80'', Color: Tipped Champagne Ivory
Absolutely gorgeous. Its got some weight to it, which I love, so cuddly. Nice quality velvet lines the underside in a beige color. Well done. Looks and feels so luxurious. The color is as in the picture, has dimension when its rumpled, but fully creamy white when laying flat. I can't figure it out how that happens lol! But its lovely.

Buy it!
Size: 60''x80'', Color: Tipped Champagne Ivory
So soft and perfect weight! The color is beautiful and it feels luxury!! Great value for money and the size is perfect. Fits over my king bed nicely, not enough to be an actual king size blanket but it’s enough to cover the main part of the bed and add extra warmth! Mine did shed a little out of the bag, but I just put it in the dryer with some dryer sheets (no heat) for an hour and that did the trick!
