Incredible Dupe
Color: Pink, Size: Throw (50" X 60")
I never leave reviews, but I was looking for a dupe blanket for my kiddos after getting a much more expensive brand blanket for myself, and this one is excellent. It’s double-sided so the same mega-soft on each side and cozy but not too heavy. I’m now getting them as Christmas gifts for everybody. A+ purchase

Oh my!!!
Color: Pink, Size: Throw (50" X 60")
This is the softest blanket ever! I sleep with it next to my skin and my bigger blanket on top because I so love how soft it is. If they ever make this in a larger size I will definitely get it!!!! LOVE THIS!!!!

Warm, cozy and thick high-quality throw.
Color: Cream, Size: Throw (50" X 60")
This is thick, non-shedding blanket - and for cold, winter nights… THE BEST. My granddaughters found it to be too warm, but not this grandma! I’m fit, but dang, these super-cold Alaska nights allow me to stay warm and cozy! If you have someone who runs a bit on the colder side, they will love this blanket! It washes beautifully. Great value!

A warm hug from this fantastic blanket!
Color: Cream, Size: Throw(50" X 60")
This is my go to blanket when I want to cozy up on the couch. So soft and warm, it’s like snuggling a hug! Washes well and lasts forever years. I replaced mine after 4 years with the same thing in a different color option! Perfect size to cover up and also a nice accent piece on the back of the couch.

In Awe
Color: Tie-dye Taupe, Size: Throw(50" X 60")
this is one of my favorite blankets I’ve ever ordered from Amazon! We use it on our couch. The colors are absolutely beautiful and stunning. It looks very earthy and kind of grounds my living room decor. It is very soft and cozy as well so it serves as many functions in my room! Probably will order another one soon for the other chair. The quality is superb.
