Large plain areas of walling can be decorated by using blue-flared or vitrified headers to produce patterns known as Diapers; these can be triangular or lozenge shaped. The patterns are created by English Cross Bond which is similar to English Bond but the joints of each alternate of stretchers are moved over by placing a header next to the quoin stretcher which gives a stepped effect to the cross joints. There are many good examples in both older and modern buildings.
