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!
