Graduated stars! The variation in the density of the fills within each star creates the shaded effect. This sample is also stitched in a variety of greys to create a second shading effect across the whole piece. The codes are given for the greys I used within the chart, but you could of course, stitch this up in all black thread, or your favourite colours.
