Great size and warm but didn't feel as luxurious and soft or thick as I thought
Color: Shadow Grey, Size: Twin/Twin XL
This blanket is not quite at fluffy or thick as I would have wanted. It feels thin but soft. It does keep me warm though and it's the perfect size to have multiple people cuddle on the couch while watching a movie?

Shed Really Bad
I love tge feel of these blankets. However, they shed really bad. We have blanket fuzzy embedded in all of our clothes from these blankets. I have washed them several times.

Light, soft, comfy, cozy, but not hot!
Color: Dark Sage Green, Size: King/Cal King
I've been looking for a blanket to replace a Berkshire blanket called "Perfect Touch" I've had since 2009 and this is it! I wanted something light weight, comfy, and cozy that doesn't get so hot like many do. When I first got it i thought it might get hot because its soooo fluffy, but it doesn't. I know some have complained about shedding or it coming apart after washing. I've washed it several times, following the washing instructions provided and haven't had any issues at all, really nice quality for the price!
Oh, and its cat approved too.

Cute for girl's dorm room! Needs a wash/dry warning.
Color: Pastel Lilac, Size: Twin/Twin XL
Wash/dry by itself. Leaves lint on anything and everything that is washed and dried with it. Kiddo learned the hard way. Loves the blanket and it's feel and color but was disappointed with the left-over pills on the rest of her items from that 1 load. Soft, fluffy and lavender. Great for her dorm!
