Loving my Bedsure Blanket
Color: Cream, Size: King (108" X 90")
I love this blanket. It’s for summer use & is the perfect weight. I feel both cozy and cool! Plus color & size are as shown. I washed it immediately and it was easy & came out soft; no shrinkage or shedding in the dryer.

Very soft. Light Blue is more of a sky blue
Color: Light Blue, Size: Throw XL (50" X 70")
Very soft, pretty thin, and a little stretchy. Overall, it looks nice. I would say it's a little thin for the colder weather, but great for the warmer months. I got the light blue, and it is a little more sky blue than true baby blue. I wish it were a true blue, but it's close enough that I'll keep it rather than go through the return process. I washed it, and little fuzzies came free, but nothing too alarming for a first wash. Hopefully, it doesn't do that every time. With how thin it is, there'll be nothing left eventually.

Super soft and strong , really nice blanket
Color: Navy, Size: Queen (90" X 90"), Color: Navy, Size: Queen (90" X 90")
This blanket is so soft. This blanket has stretch to it which is nice for tucking under mattress. Easy to lay out and fits perfectly on a queen bed, perfect amount of hangover. Great quality blanket. I did wash before I put on the bed and it did great. Shed in dryer but that’s easy clean up in vent. No shedding on bed after washed. I laid on bed before washed and it only shed a small amount, not much. I absolutely love this material, strong yet super soft. Definitely a great blanket to buy! You’ll love it.
