great addition to bedroom decor, soft and lux
Color: Tie-dye Sage, Size: Throw(50"x60")
I purchased this for my daughter for a gift. The softness Is next level.. The quality is greater than I expected and feels lux. It's thick without being too hot. It's a beautiful addition to their bedroom decor. It had no weird smell or order, and fit just as described. Ive washed a couple times and its holding up great.

Soft and cozy
Color: Tie-dye Cream Beige, Size: Twin(60"x80")
Recieved last week. The texture is soft and warm. Love it so far. The beige color is a little more greige than I expected but it still goes well with my decor.

Amazing blanket. Definitely recommend!!😊
Color: Tie-dye Sage, Size: Twin(60"x80")
Best blanket ever. I got it for an Amazon a lightning deal for 55% off! It was only 22 dollars and this is the most comfortable blankets ever. It is very soft and it keeps me very warm. I would definitely recommend it, it's even more beautiful in person. It's very high quality, and it's lightweight but keeps you warm. Though I wish they would lower the price, because it's 70 dollars to buy another one. But still an amazing blanket, 5 stars for me!!! 😊😊🥰🥰😍😍🤗🤗💗💞

Fabulous and sooooo soft
Color: Tie-dye Khaki, Size: Throw(50"x60"), Color: Tie-dye Khaki, Size: Throw(50"x60")
This blanket is so extremely soft and cozy. The only reason I deducted a star was because the fur side and the velvety side aren’t sew together anywhere besides the edges/seams, so when I fold it it’s basically like 2 blankets just sewn together and not one blanket. When you lie with it and cover you, they sort of separate if that makes sense but it doesn’t bother us. It’s so comfy to have on the couch and while movie watching. The only time it sort of a pain is when I fold it. In saying that, I would buy again. The velvety side is a soft tan/beige and the fur side is creams, off white and variations of the tan/beiges. So lovely. You can see it next to a solid cream colored blanket I have that I also bought on Amazon. It matches well and I love it!
