Excellent quality; fit may be tight
The quality of these covers is very good. The feel is soft and warm. The color is rich. They wash easily and well. My only problem is the fit. My 15” throw pillows are overstuffed, and they won’t fit in these covers. If your pillows are not overstuffed, I highly recommend these.

Really like these for the price
I was surprised when I received these because they are made better than expected. The color is accurate and they are nice and fluffy. Hidden zipper works well too. We will see how they wash when the time comes, but I usually bag items like this so should be fine.

Luxurious feel
Color: Light Brown, Size: Throw (50" X 60")
This blanket is soft and fuzzy. It has a little weight to it so it’s great to snuggle up on the couch with. Double lined makes it feeling luxurious. Haven’t noticed any shedding yet I’ve had it for a month and have washed it a couple times.
