Great for the price
Size: Full, Color: Bright White
Great for the price. The fabric is thin and not made well but for the price it’ll do. Must iron it so that it lays correctly but I figured I’d have to.

Awesome product
Size: King, Color: Navy Blue
From this point forward, this is the only company that I would use. All is one color, and not having the white fabric in the middle is a bonus!
