Grunge is the creation of Rachel Benchley and has been part of every Basic Grey collection since her first Urban Couture collection in 2008. It became a Moda Basic a few years ago with new colors being added every year.
Grunge is a unique fabric that is dyed first, then printed on one side to create a unique, textured look. While the printing is the same for all Grunge fabrics, the final look of them can vary widely depending on the number of colors applied, the subtlety or contrast of those colors, and so on.
2.5″ x 2.5″ fat quarter squares will yield a fair amount of variety in the look and color in each. It can also be used on the wrong-side as a solid – as a single characteristic design or just to add a little variety to your projects.
