Soft, velvety and very pretty.
Happy with this blanket. A bit thin, but I use it for layering so it is perfect for that. The color is a deep, rich purple. Which can be hard to find. Does not shed at all and feels very comfortable against the skin.

Fuzzies
I've waited to write this review to see if the fuzzies would go away. I've washed these blankets 4 times, twice when I first got them. The shedding was really bad on the first two washes, and each time I launder them, I hope they're gone, but no, I have to spend time picking them off, and I continue to do this, because the blankets came at a great price, they're a perfect weight, soft and cozy. Just beware if this would irritate you.

Another Berkshire Favorite!
So soft and silky and warm and, oh the butterscotch color is such a perfect fall color! No static either! It does come rolled and sealed with plastic in a box, which I appreciate because you know you’re not getting something someone used and returned; all the Berkshire products I’ve bought come this way and while things being squished and sealed in plastic normally irritate me I approve of it here because Amazon is notorious for sending out used dirty crap and no one wants that in a blanket. Luckily with Berkshire I feel assured I’m always getting something new. Maybe that’s because the products are so high quality no one wants to return them (I know I don’t)! Or maybe they don’t allow returns, I don’t know. Sorry random tangent! But anyway, buy this for you, your friends, your pets, a stranger on the street! I don’t know, but I’m pretty sure the soft cozy feeling of this blanket could ensure world peace if everyone has one because everyone would be cozy and comfy and happy. Well maybe not everyone there’s always someone who has to complain. But not this girl. Because I’m cozy, comfy, and happy under my awesome blanket while I write this review!

Great!
It was great and soft! Very warm so maybe not a summertime blanket if it gets really warm by you! It’s really pretty and looks just like the pictures!
