108″ Grunge Hits the Spot – Cobolt is 100% cotton fabric that is 108″ wide. Designed by BasicGrey for Moda Fabrics, it perfectly complements the rest of Moda’s very popular “Grunge” line. The blue wide back fabric has a textured print that’s reminiscent of brush strokes with fun polka dots. The dots are about 0.5″ in diameter. It would look lovely on the back of a modern quilt, or use it for the piecing on your next quilt top! The cotton is soft and luscious, it would feel wonderful on the back of any quilt!
