Great throw blanket with lots of fuzz
Color: Pink Ribbed, Size: Throw(50"x60"), Color: Pink Ribbed, Size: Throw(50"x60")
Very soft and cozy throw blanket, very pretty light pink color. It's big enough for one person like most throw blankets. Crazy coupon lady cued me into a discount so I got for a great price. My only complaint is that it leaves fuzzies everywhere- I highly recommend washing it before using- see pictures. Over all though a great throw blanket - soft and breathable fabric- worth the cost, but I've never seen a blanket throw so many fuzzies out of the package. Recommended, unless you're wearing a black suit.

Great price for such a warm, soft blanket.
Color: White Ribbed, Size: Queen(90"x90")
Super soft blanket that I lay across my bed but I have taken it on road trips to snuggle up with in the car and will use it when curling up to watch a good movie. Not very thick but is certainly warm. I ordered white and I absolutely love it. The texture adds nice contrast to my comforter.
