Whirlpools – Black is an extra wide backing fabric from Wilmington Prints. It is a black and gray print with concentric circles. The pattern is clear but the monochromatic color palette keeps it from being too busy. The black is actually a mix of several different grays. As we know, there are different types of black. This one is on the beige edge of the spectrum. Therefore, this backing fabric will match well with a variety of blacks and grays in quilt tops.
