72" X 72" finished as presented, easily add borders if desired, or can be enlarged by creating additional units using extra 2 1/2" strips.  Jelly Roll© friendly.  Easy Saw tooth blocks created from simple strip piecing.  Requires 20 fabrics, two 2 1/2" strips each for best result.  Can be scrappy using 40 fabrics one strip each.  Much easier to create than it looks.
