Soft, Warm, lightweight, Cozy
Color: Cream, Size: Full/Queen
When I first received this blanket I washed it by itself in cold water with detergent. I did not use a fabric softener or a fabric sheet. I air dried it completely and then put it in my dryer on air fluff for 10 minutes. No shedding and it came out just like I received it. I was concerned about shedding with some of the reviews but I had no issues with that whatsoever. It's warm yet lightweight. I didn't want anything that would make me overly hot because I'm always hot anyway. It takes that cool edge off when you still want your overhead fan on. My daughter said she likes it better than the one she has. I can't remember the brand. I feel it has a good quality. Just make note to wash it as instructed and it'll hold up well and look just as nice as the way you bought it. I'm not sure how the other reviewers that didn't leave 5 stars washed there's, but it couldn't have been the correct way.

Soft, warm, sometimes shed
Color: Shadow Grey, Size: Full/Queen
LOVE these blankets! The only downside is some of them shed. They will keep you so warm and they are very soft.

Great size and warm but didn't feel as luxurious and soft or thick as I thought
Color: Shadow Grey, Size: Twin/Twin XL
This blanket is not quite at fluffy or thick as I would have wanted. It feels thin but soft. It does keep me warm though and it's the perfect size to have multiple people cuddle on the couch while watching a movie?
