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!

Nice dark blue color
Size: Twin, Color: Navy Blue
Bought 2 dark blue for twin beds and they look good with my blue and white quilts covering the beds. There are some wrinkles in the cloth due to packaging which may relax with time. but don't show much due to the dark color. I did find any defects in the stitching or fabric on the items I purchased.
A note for prospective buyers is that the dust ruffle covers the entire bed foundation, so get help to put on under a heavy mattress.
