I like to use a dark navy. It sets off so many colors.

Here's a few of mine .........

I've never used a dark background, but I am loving all the beautiful quilts everyone has shared here. I had enough trouble sewing black binding onto a quilt with a black border! That was my first Bonnie Hunter mystery, Allietare! I guess the darker the background, the brighter the blocks will have to be. Is that everybody's experience?

I like quilts with dark backgrounds. They can be very attractive as long as they are hung on a light wall/backdrop.

Here is one that I did with Kaffe fabrics with a dark purple grunge as a background. So far out of my comfort zone but I was very pleased with the end result.

Here's a quilt I did several years ago. My great-niece loved it, so I gave it to her. It has a minky back.

Here are a couple I made.

I made Bonnie Hunters Chilhowee mystery with black background. I call it Chilloween.

Here's a string quilt with gray background

I have made only three dark quilts. I have a problem enjoying making and finishing them. But, I made this lap sized one for hubby last year.
And this one for my grandson. Not very dark really.
And last is the one for my son.
