I don't live in the "country" but dust really can accumulate. The way I look at it is if the fabric can get dusty, it is also in danger of fading. Using shelving with doors is not an option for all of my fabric stash. So I use a few quilt tops that I will never get around to quilting. Someday I might actually quilt them so they will be more washable, but for now I just shake them out.
