quality gets worse over time
have had these for a while now, they were better quality when i first purchased them. i flip them inside out before washing and they just end up scraggly and weird textured after i wash them. i’m not sure if i’m doing anything wrong when i clean them. not a terrible price for what you get, i just wish they were slightly better quality

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!
