It’s been a few months and I still get excited about my blanket
Size: Throw(50" X 60"), Color: Olive Green
20x better than I expected! Has a great weight to it so it kept me extra warm during those super chilly nights, but SOFT. Like SO SOFT!!! I was skeptical about spending this much but it turned out to be worth it. Color is great too it’s like a forest jade green
