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.

soft, cozy, lightweight. Drapes nicely or folds flat & even. Warm as liner to another blanket
Color: Orange, Size: Twin(60"x80"), Color: Orange, Size: Twin(60"x80")
Summer weight, soft feel, cozy. If using in cooler temps, then consider using it as a liner, then toss another blanket on top. Nice cozy way to trap in heat.
I love orange and was looking for a functional throw blanket. I didnt want the typical lap blanket size (50"x60"). I am tall and wanted something I can tuck my feet under and pull up to my chest when on the couch. But I also wanted it to be decorative when not in use. Not wanting a thick blanket for this purpose, I looked for a thin one of this style. It folds small and flat, OR drapes nicely when tossed. Even at twin size (60"x 80"), it still works as a "throw" blanket. It measures a little wider and aittle shorter so not perfect twin length.
It is thin, but not see through. Very soft. Haven't washed it yet, so hopefully it holds up.
ALSO, we have cats and dogs, so I am always looking at something to see if it can also be used for them. Depending on size, these blankets would make good furniture covers. Nicer than sheets, cheaper than pet products, thin enough to toss in washer, and a material that will stay in place on fabric furniture. Or just a blankey for pets that like to get cozy.
WHICH, at the time of my writing this, my recent rescue dog from the south is experiencing the cool fall temps of fall. She is snuggled up tight against me. I have this blanket as the base on me and the couch, and then a thicker fleece blanket on top of me and her. I just took a pic and will include it.
