Installment No. XI of a serial on weaving in the journal Engineering, explaining diaper weaving, in which two or more divisions of harness and treadles are combined to weave large checker or diaper patterns for tablecloths and shawls. It describes a two-division harness with its threading and treadling plans, the twills that fill the pattern squares, and a mounting that controls up to twenty leaves with a single set of treadles using coupers, levers and handles. It closes with the construction of healds, leashes, lingoes and the comber board for figure weaving.
