Soft blanket
Size: Queen, Color: Ivory
Just as pictured. Soft, comforting, warm. This blanket is my favorite when I snuggle up in my chair to read. The green color washed very well, no shedding. (My child’s purple one left a lot of fuzz in the laundry, so I would advise washing that color alone.)

The width!!!!!
Size: California King, Color: Ivory
I've purchased this blanket several times. It's the only blanket I've found which is wide enough to tuck into my California King (Tempurpedic) mattress. Nice color selection. Soft and comfortable, like most modern fleece products.

SO SOFTTT!
Size: King, Color: Chocolate
Oh em gee! This is the softest blanket I’ve ever owned, I sleep SO good because of how buttery the blanket is. It’s breathable but also not super breathable, I personally like the “mid” weight of it, I’ve ordered a few prior and they were too thin for me, this blanket is perfect for me. Would definitely recommend and I want to buy all of them, and the price is perfect for me!
