Good cover for furniture, soft and easy to wash.

These are great for covering couches, chairs, ect. The only problem you will have is keeping them in place.

Great blanket!
Color: Black White, Size: Throw(50"x60"), Color: Black White, Size: Throw(50"x60")
I originally bought this to use in photos for my son’s race themed birthday. It looked perfect with the checkered pattern. But it ended up a favorite blanket in our house because it’s sooo soft!
