Best blanket ever!
Color: Onyx / Camel on Ivory (Double-sided Faux Fur Bubble), Size: Throw (50" x 60"), Color: Onyx / Camel on Ivory (Double-sided Faux Fur Bubble), Size: Throw (50" x 60")
This is so soft. I just want to keep petting it. I love that one side has different colors. I am blown away at how good this feels agains my skin. It even feels good over my lap when I have pants on. I would highly recommend this blanket. I will probably be showing all of my friends. I just hope it keeps its softness and is a good quality. If anything changes I will update.

My mom loves it
Color: Onyx / Camel on Ivory (Double-sided Faux Fur Bubble), Size: Twin (60" x 80")
This was a Mother’s Day gift for my mom. She absolutely loved it! It’s double sided, which is hard to find on Amazon. It’s super soft, and not too heavy! The quality feels like something that is high end too!

FAUX RABBIT FUR THROW
Color: Brown (Faux Fur Bubble + Flannel), Size: Throw (50" x 60"), Color: Brown (Faux Fur Bubble + Flannel), Size: Throw (50" x 60")
This throw has a soft feel to it, like you’re holding a Bunny. It’s beautiful and has a nice backing on it. I have to say I do not find it a good value for the money thinking about long term use goes. Perhaps a small child might use it as a form of comfort. I probably wouldn’t buy it again.

You can’t tell the difference between this blanket and my Pottery Barn ones.
Color: Cream White
I absolutely love this blanket! It is incredibly soft and plush—honestly one of the coziest blankets I’ve owned. The thickness makes it feel high quality, and it keeps me warm without feeling too heavy.
The cream color is beautiful and neutral, which goes perfectly with my home decor. It looks just as good in person as it does in the photos. I also love that it has that luxe, fluffy look that makes any space feel more cozy and elevated.
I actually own blankets from Pottery Barn, and I truly cannot tell the difference in quality or feel. This one gives that same high-end, luxurious vibe for a fraction of the price.
I’ve used it on the couch and for relaxing at night, and it’s quickly become my go-to blanket. So far, I haven’t had any issues with shedding, and it seems very well made.
I now know exactly what I’ll be getting everyone for Christmas—this is such a perfect gift!
Definitely worth the purchase—would 100% buy again!

Color: Cream White
I’m obsessed with this blanket. It’s insanely soft and cozy without feeling too heavy. The cream color is even prettier in person and looks so clean and elevated. It’s perfect for lounging or just throwing over a bed or chair for decor.
I’m so happy with this purchase, definitely worth it!
