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.

Lightweight yet warm
Color: Blue Moment, Size: King (90 in x 108 in), Color: Blue Moment, Size: King (90 in x 108 in)
I got this blanket for my hubby and I to use at his parents house -- I got the king to use on a queen bed. It is very soft and fuzzy -- the cats really like it. It is very lightweight but keeps us warm on slightly chilly spring mornings. It machine washed and dried well with almost no lint. It looks good too. This review is for Berkshire Ribbed VelvetLoft® Blanket – 330gsm Medium Weight Plush, Extra Soft & Warm Plush Blanket for Bedroom, Couch, Travel – Durable & Easy Care(Blue Moment, King Size 90" x 108")

Mediocre blanket, not usual Berkshire quality
Color: Irish Cream, Size: Throw (50 in x 60 in)
Got to admit, wasn't overly impressed with this blanket. It came shedding like a dog out of the box. And it's pretty thin. I've bought quite a few Berkshire products and been very impressed, but this particular blanket I wasn't too impressed with..

Juicy couture throw blanket review
Color: Juicy Emblem Hot Pink, Size: 50"x70", Color: Juicy Emblem Hot Pink, Size: 50"x70"
Amazing blanket. The black color matches with the black comforter underneath. It's incredibly warm and soft and doesn't have any. It's quality is absolutely worth the cost. It's the perfect amount of thickness so that you don't overheat but that you are also not freezing. There is no shedding or fuzz That sheds. I think so cute.
