A woman in Ohio painted a quilt square on her barn in memory of her mother and the that was the beginning of the Quilt Trail that extends into Kentucky. There are three of these barns between Berea and Richmond.
Why are the barns black? Because black paint is cheaper than red. There are a lot of black fences around too because the black paint is cheaper than white.
There is a book on the Quilt Trail for any quilters who may be interested in more information.
