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!

This one is really soft
Color: Tie-dye Khaki, Size: Throw(50"x60")
This is actually baby bunny soft! I was very pleasantly surprised. The top side is plush and the bottom side is smooth but in a velvety suede type smooth. It is very well made and after machine washing and drying it several times it still looks and feels new.
