Figure 105.—Basket (si'u ola) rim twist and join (so'o):

a, The leaflet towards the butt end (1) is twisted over 2, then 2 over 3, and so on throughout the strip. This resembles the twisting technique followed in the laulau platter but is simpler, being confined to one leaflet strip whereas in the platter a pair of strips were treated together. The other strip supplying the sinistrals is similarly treated. The two double strips are then placed in position for plaiting with the midrib strip towards the worker and the sinistral bearing strip uppermost. The fa'a'au commencement by horizontal twilled twos is the same as in the wall screen but the first dextral is raised beyond the first sinistral and kept raised until the second and third sinistrals have passed under it to establish the twill. The two midrib strips are kept close together throughout and the si'u ola has thus a neat twisted rim in which the midrib strip cannot be seen from the outside. This contrasts with the rougher rim of the ola tu. In Tutuila, the dextral wefts were more commonly supplied by one strip without the leaflets twisted. In twisting the leaflets, the first leaflet twisted over that in front of it has no leaflet passing under the arch that it forms. Also the last leaflet has no leaflet left over which it may be twisted. When the ends of the midrib strip are brought together, the first empty arch is shown by (1) and the last leaflet by (10) b, The last leaflet (10) is then simply passed under the arched first leaflet (1), drawn taut, and the join is completed. The outer sinistral strip is similarly treated. The filling in of the end gap between the marginal wefts is then carried out for the join is not made until the working edge has reached the end of the strips.
