Soft, plush, lovely
Color: Blue Moment, Size: King (90 in x 108 in)
We got this blanket in king size to use in lieu of a comforter in the warmer months. It's incredibly soft and luxurious. It's thick enough to feel plush and heavy, but thin enough to be perfect for a cool summer night.
It feels like really excellent quality, too. This is not cheap thin fleece. I've only washed it once so far, but it seems like it'll hold up to many washes. It's big, though, at least in king size. It takes up pretty much our entire washing machine, so it needs to be washed by itself or with little else. To dry, I tossed it in the dryer for 40 minutes or so on medium heat and then hung it over a banister to finish drying, and this seemed to work well.
It's also a very pretty blue, like a dusky light blue, just lovely. Overall, I'm very happy with this blanket.

A good lightweight blanket
Color: Blue Moment, Size: Twin (60 in x 90 in), Color: Blue Moment, Size: Twin (60 in x 90 in)
With perpetually dry hands I have issues with certain fabric textures. This Velvetloft blanket is on the border of triggering, but nothing like how the Classic Extra-Fluffy Plush throw is. The ribbing is interesting visually, but also made the blanket feel a lot lighter too. Definitely one I'll keep on the couch for a chilly day and not for my bed.
When I washed it I was expecting a lot of shedding like the Classic one, but there wasn't as much. I washed it on cold and dried it on the delicate setting since I don't have a good place to air dry. It doesn't appear any worse off than before I washed it.
Overall I like this one way more than the Classic, but the Primalush wearable blanket is still my favorite.

Wait until you unroll this beautifully soft blanket! It’s the one you want.
Color: Goose Egg, Size: Twin (60 in x 90 in), Color: Goose Egg, Size: Twin (60 in x 90 in)
I can’t pass up a good blanket, and boy is this one impressive! It’s another high-quality product from Berkshire Home Company.
What I love about my goose-egg colored, velvety soft, blanket is the ribbed design. The lines separate the elevated design, and I could literally rub my hand over it throughout an entire movie!
It’s SO plush and soft. It’s made from their signature VelvetLoft fabric. Plus the design makes it look like a planned piece of your decor. I like the color I chose but there are others to choose from as well.
It’s nice and thick but not too warm. I got the 60”x90” twin size which is great for me! Next time I will get a queen size to go over my bed.
The price point is so low for the quality you get! You should stop your search now because this is the best one!

Luxurious VelvetLoft From Berkshire
Color: Stormy Weather, Size: Full/Queen (90 in x 90 in)
Berkshire hits it out of the park with yet another fabulously lux blanket. Their VelvetLoft is my favorite for warmth and softness all while looking like an offering at a high end hotel or B&B.
The medium weight was the perfect choice to pair with the large ribbing and while this IS the blanket to choose once the leaves start to fall, it's almost sinful to snuggle up with to watch a movie with the AC humming in the warmer months since it washes like a dream and did not shed at all.
I used cold, delicate and my favorite scented delicate wash. Dryer on Medium for 10 minutes and then Low for anther 20 minutes. Perfect!
The Stormy Weather is a silvery gray neutral and will work with multiple coverlets, bedspreads and quilts.
Perfect gift! Definitelythe blanket you want in the guest room!.

Beautiful blanket
Color: Goose Egg, Size: King (90 in x 108 in), Color: Goose Egg, Size: King (90 in x 108 in)
Really loving this blanket. It’s just beautiful - a step above the average chenille seemingly sold at every drug store/grocery store/shop. Has a lovely sectioned pattern and is generously sized for a king blanket. Plenty of room on both sides of our deep king mattress.
Washes up very nicely.. still like new! Note of caution: The label says air or line dry, no heat. Usually I wouldn’t consider any vexing that can’t be regularly washed and dried. But since every chenille shrinks some.. I was careful to machine wash cold abs air dry in drier only and it didn’t shrink at all (go figure). Came out of drier nice and soft still.
Great value for this price. Would also make an excellent gift for housewarming/wedding etc.
