Great summer blanket.
Color: Black, Size: Full/Queen (90 in x 90 in)
I purchased this Berkshire 3-layer fleece blanket, and it has quickly become my go-to for my queen size bed. It fits perfectly with plenty of overhang, making it look great as a top layer or a middle layer.What I love most is the breathability. While the material is technically fleece, the 3-layer design provides a nice "cotton-like" feel that doesn't feel heavy or stifling. I tend to sleep hot, and this blanket does a fantastic job of keeping me cool and comfortable through the night while still providing just enough cozy warmth.At this price point, the value is good. It feels much higher quality than other thermal blankets I’ve tried, and it holds up well in the wash without pilling or losing its softness. If you're looking for a versatile, lightweight blanket that works year-round, this is a solid choice. Highly recommended!

Fab , chic, furry & perfect for HTX weather
Five stars because I’m super picky about my main blanket and after two years I finally found one that will be as good as the one with 70 holes that I’ve been holding onto like a 7 year old. It’s super furry, and soft and the solid black side is smooth. Its not too heavy , its the best kind of thin which is perfect for Houston Texas. It’s just how I like my go to blanket. I have tons of blankets but there’s always one that’s my most favorited and now, this one will be for the next however many years. It’s a FAB design too. Love!

My Toddler’s Favorite Blanket – Soft, Adorable, and So Cozy!
Size: 50" X 60", Color: Cow Print Brown
My 2-year-old is completely blankie-obsessed, and this cow print throw has become his new favorite! As soon as we opened it, he grabbed it and hasn’t let it go since. He drags it from the couch to his bed, to the car, and even tries to take it outside—it goes everywhere with him. The faux fur is incredibly soft and fluffy—seriously cozy without being too heavy. The size (50x60) is perfect: big enough to snuggle up in, but still manageable for a toddler to carry around. And the cow print is absolutely adorable—it adds a cute, rustic touch to our living room too. It’s also held up great after multiple washes (a must when it’s a toddler’s constant companion). No shedding or matting, just the same soft texture every time. If you’re looking for a cozy, kid-approved blanket that’s both functional and stylish, this one is a winner!

Beautiful blanket - Matches Pillow Cases perfectly.
This is a beautiful blanket that matches the pillow cases the seller sells in the same pattern and color perfectly. The twin size I purchased is thin as many have said but it is also heavy which is kind of strange. The inside on mine is a velvet type material that is very soft and warm. Some have stated theirs is a silky cold material but I can say mine is not. It is going to work great as the extra blanket on my bed, especially since it matches the pillow cases so perfectly. I did see some were complaining about what happens when you dry it, it basically looks like it melted but really just gets all matted. This happens with most blankets and other items like this. I can say I learned the hard way when I purchased my very first fuzzy blanket a few years ago and washed and dried it immediately only to have an unusable mess come out of the dryer. Since then I wash on gentle and dry mine on air dry with absolutely no heat and have had no problem at all.
