Pretty good blanket. Slightly larger than normal throw.
I purchased this leopard print throw blanket because you can get it in twin size and twin size is a lot more usable in not only a bed but also on a couch. Like if you have two people sitting next to each other, it's a lot easier to use the twin size than a throw size, which I feel is a little bit cramped.
In addition to that, I saw in the picture that this looked almost like fur. Now when you look at it in person, you can clearly tell it's not for it's got almost like a a spotted pattern even with the spots. And while I don't know if leopards actually look like that, certainly at a distance, it feels a lot more accurate than things that are only vaguely leopard printed like the the common pink ones, as you can see here in the other variety. But certainly the Brown leopard one looks good.
Plus, it is comfortable and pretty soft. It's softer on one side than another side, but only slightly and while it's rolled over and stitched at the edges, it is a single layer throughout. So it's not going to give you a ton of warmth. But I will give you some warmth, you know just enough to be nice and that means you can use it year round.
So overall at this price for a twin size leopard print throw. I think this is a good deal. Well I think it could be a better deal. I've certainly seen worse so I think I could recommend this product

Pink cheetah blanket
Color: Pink Leopard, Size: Throw(50" x 60")
I recently got this pink cheetah print throw blanket, and honestly, it’s such a fun and cozy addition to my space. The first thing that stood out to me was the design—the pink leopard print is super cute and adds a pop of personality to my couch without being too overwhelming.
The material is really soft and lightweight, which makes it perfect for everyday use. It’s warm enough to keep me comfortable while lounging or watching TV, but not too heavy where it feels bulky. I also like that it’s easy to fold and move around, whether I’m using it in the living room or taking it to bed.
Size-wise (50” x 60”), it’s a good throw size—great for one person, though if you’re looking to fully wrap up, it might feel a bit small. The quality feels decent for the price, and it seems to hold up well after use without shedding.
Pros:
• Super soft and cozy
• Cute, trendy design
• Lightweight and easy to use
• Good value for the price
Cons:
• Slightly small if you want full coverage
• Not the thickest blanket for colder nights
Overall, I’d definitely recommend it if you’re looking for something stylish, comfy, and affordable to decorate your space while staying cozy.

This is a fabulous LIGHTWEIGHT blanket exactly as advertised!
This blanket is exactly as described, it is LIGHTWEIGHT meaning it is thinner and cooler than some of the other Berkshire lines of thicker heavier blankets.
I have purchased at least 20 Berkshire blankets/throws for myself and for gifts because they are the absolute best quality at a seriously reasonable price. They are so soft and comfy and they will survive years of regular use and washing.
This one is a gorgeous deep purple and is the perfect weight for our recent 85+ degree days in March with nights that still need more than a sheet but less than a comforter. It measures true to size after a thorough wash/dry cycle and I have had zero shedding issues so I’m not sure what other buyers are doing but please wash your blankets before using them.
The photos show this gorgeous purple in a twin size next to a twin “Ombré Burgundy classic heavyweight” (omg go check that one out) and you can see the purple one is just about half the thickness of the other one which is exactly what I wanted for the hotter summer months coming up.
If you want a thicker blanket, Berkshire makes a lot of them, just look for the ones marked “HEAVYWEIGHT” instead of going through the hassle of returning a blanket that is clearly advertised as a “lightweight soft fuzzy plush blanket or throw” and then getting mad because you got a lightweight soft fuzzy plush blanket or throw 🤣

Beautiful quality, huge, cozy, love it!
Color: Dress Blues, Size: Oversized King, Color: Dress Blues, Size: Oversized King
I really love this blanket. This blanket is super soft and has a velvety feel to it! It is so comfy! The quality is excellent, it feels beautiful and does not feel cheap at all! I love laying on it and the soft texture, it’s so soft and cozy. It has a nice weight to it but it is not too heavy. It’s very warm. This blanket is honestly huge and that’s the reason I bought it. I bought it for the size. I wanted something large enough to protect my new couch until my dogs learned to stay off of it. They would come in from outside being really excited and jump on the couch, this blanket helps to protect my couch. It does not fall off because it’s large enough to completely cover from the floor to the back behind my couch and my couch is more of an oversized. This blanket washes beautifully, it looks the same as it did when I first bought it after washing. I washed on cold and when I dried I did low heat. I ordered the blue and the color is very nice. I got a great price on this blanket when I bought it, the blue was on sale. I would definitely buy again! I am very happy with it!

Soft, even airdried.
Color: Butterscotch, Size: King/Cal King, Color: Butterscotch, Size: King/Cal King
I needed a larger, better match in color to protect my sofa from our pets. It is very soft even after hanging to dry. It dries very quickly. It did not shed in the wash. If you plan to machine dry keep in mind the fact that no or low heat is necessary. The color worked out for my needs. I recommend it.
