Openwork motifs add visually stunning lace to the yoke, which frames the face beautifully. By making the motifs pentagons rather than squares, you not only add extra width at the lower edge (creating the increases required for a sweater yoke), but also give you a wonderful scalloped edge from which to continue the body of the sweater in a chevron pattern. The rest of the sweater is worked even in pattern. Buttons offer a casual closure but it can be beautifully worn open as well.
