Figure 112.—Pandanus mat (paongo) double weft commencement:

a, the two double wefts are laid parallel in a diagonal direction leaning towards the left, a point (see arrow head) is selected somewhere towards their middle for making the corner, and the upper element of the right weft (1) is raised out of the way; b, the lower element of the right weft (1') is then bent upward at right angles with a half turn and turned to the left over both elements of the double weft (2, 2'); c, the upper right element (1) is then straightened out and bent with a half turn backwards around the bend already made by the lower element (1') and turned to the left to pass between the two elements of the left weft (2, 2'). To do this the upper element (2) is raised with the left hand and after the turned weft (1) has passed over the lower element (2'), the upper element (2) is dropped back over it. The bend made by both elements of the right weft forms the far edge of the corner. The principle may now be laid down that, in bending weft elements to form a marginal edge, the upper element of a double weft will always be bent backwards and the lower element upwards. Furthermore, in interlacing two double wefts, the check technique must be maintained with the individual elements. Hence the two elements of a double weft must not be separated from each other by more than one element of another crossing weft. When the lower element (1') was turned forward over both elements (2, 2') of the crossing weft on the left, the upper element (1), when it was turned backwards had to pass between the two crossing elements (2 and 2'). The above principle applies only to turns at the corners and the marginal edges of the mat. d, The right edge of the corner must now be formed by the lower ends of the right double weft. It is obvious that the lower element (1') on being turned forward to occupy the upper position must pass below the upper element on the left (2) in order to comply with the check technique. The upper element (1) on being turned back must pass below the lower element on the left (2') or in other words below both left elements. It is more convenient to commence with the latter movement. Both elements of the left weft (2, 2') are, therefore, raised and the upper right element (1) is bent back at right angles on itself, passed to the left and the left double weft dropped over it. e, The lower right element (1') is now bent upward at right angles around the margin defined by its weft mate (1), the upper left element (2) is raised and then dropped over the right element (1') after it has crossed the lower left element (2').
