So Soft!
Size: 50" X 60", Color: Cheetah Print Brown
This is the softest coziest blanket! It's a good medium weight, and does not shed. It's the one I grab every time I need a blanket.

Best blanket EVER!
I honestly LOVE this blanket! I never thought I would be so in love with a blanket, but here I am! I’m planning on buying more to safe as replacements for this one is old. When I first got it, I was skeptical I would like it or not. It was so much thinner than I expected and the shape was an odd shape (long and narrow, not a square shape like I’m used to my blankets being). To me it resembled a rug more than a blanket. But, from the first night of using it I was OBSESSED! It keeps me warm and is SO comfortable! I use it on either side, and it keeps me warm either way. If you are debating purchasing this blanket! DO IT! You won’t regret it! Even my cats love it!

Functional Stuffed Animal Storage
Size: L For Adult, Color: Ombre Purple (Cover Only)
This bean bag cover solved our stuffed animal takeover! It’s super soft and fluffy too! The adult size one is really large and cozy! -make sure you have enough to fill it with! It can fit stuffed animals, extra pillows, and blankets too! We love the purple color! It’s been dragged here and there and is holding up well.
