Figure 108.—Mangaiari triple triangle, preliminary decorative stage. In all figures front of foot is to left. Sennit turns are in two oblique series but will be referred to as vertical and horizontal. They follow similar courses on near and far sides of foot; on near side, vertical turns run upward and backward and horizontal turns backward, while corresponding turns on far side run in opposite direction. a, commencement end (0) is bent around front edge near neck; first turn (1) is vertical toward upper back corner; braid crosses small posterior surface obliquely downward (a′, 1) and makes a forward horizontal turn (dotted line) to front edge. b, braid forms first horizontal turn (1′) on same line as on far side, crosses posterior surface (b′, 1′) from below upward to cross upper surface reversing course of a, 1 and makes first vertical turn downward on far side to front edge, where it crosses commencement end (0). c, coming around front edge, second vertical turn (2) diverges to run parallel on left of first turn (1), crosses upper surface diagonally to pass obliquely across posterior surface (c′, 2), whence it makes second horizontal turn on far side above first horizontal on that side, and reaches front edge. d, crossing front edge above first horizontal, the turn (2′) crosses the posterior surface (d′, 2′), corner of upper surface, and makes second vertical on far side to reach front edge with required spacing above second near vertical (2). e, third near vertical turn (3) passes over upper surface diagonally to cross posterior surface (e′, 3) to right side of second vertical (2) and above it on far side; it then makes third far horizontal (dotted line) to reach front edge above second near horizontal (2′). f, third near horizontal turn (3′) passes backward to hook around near corner of posterior surface (f′, 3′) to form third far vertical which descends to front edge. g, fourth near vertical (4) passes up on left of third vertical (3) and loops over upper surface (g′, 4) and around far margin and lower apex of posterior surface (g′′, 4) to reappear on near side below first horizontal (1) to form fourth near horizontal (g, 4′) which crosses front edge parallel with first horizontal (1). h, braid forms fourth horizontal on far side below and parallel with previous horizontal, makes reverse loop (5), and descends on far side to complete fourth far vertical (5). [It will be noted that first three verticals near and far cross small posterior surface, and corresponding horizontals form on opposite side. The three posterior crossing turns from either side cover posterior surface, as shown in a-f. After this, turns take a complete loop around projecting heel, so that both verticals and corresponding horizontals are on same side, as shown in g, h. Horizontals, however, are now below preceding horizontals, so that verticals and horizontals converge toward each other to fill in uncovered space. First loops on either side of posterior surface set line of subsequent loops which must be parallel to first, and as loops get larger a third set of oblique turns are formed which cross between upper and back edges of heel and foot.] i, shows heel and foot covered; turns parallel with first loop (5) from far side are succending loops formed from far side while far side has corresponding loops formed from near side, as in g, 4.
