I made my son-in-law a "brick quilt" for Christmas. I used over 30 fat quarters of dark browns, blues, greens, reds, purples, blacks mostly tone on tone or read as solid fabrics. I picked them all at once of quality fabrics. The bricks finished 3"X6' in off set rows. It is very rich and is a really nice man quilt. I needed fat quarters to get the nice variety of fabrics.
