407. Rectangular hanging trays would seem to be of about the 
most primitive type of plaitwork met with, and, like the preced- 
ing, it is a question whether they should not be regarded as baskets. 
The foundation is made of a right-angled plait of the one-over-and- 
under (checker) type (sec. 106), having each strand at about its 
own width apart from its parallel neighbor. Upon completion of 
this base, which is more or less square, the projecting ends of the 
strands along each of the four sides are collected into three portions 
and worked into a triple plait 
(fig. 108), these four plaits be- 
ing ultimately bent up and 
knotted together on top, very 
much in the same style as a 
laundry woman would tie the 
corners of a square sheet over a 
bundle of washing. Made of 
itiriti. For use, it is suspended 
from a beam by a thread tied to 
the upper knotted portion.

foundation plaited on the flat. 
The following describes their construction as observed among the 
Warrau (pl. 98 A): Starting with two pairs of (itiriti) strands 
placed at right angles, a square foundation of from 18 to 22 
inches in width, exclusive of the free ends of the strands pro- 
jecting to a distance of another 8 or 10 inches, is finally com- 
pleted, a common pattern depicted being a series of concentric 
squares (fig. 109 A) having their diagonals at right angles to 
the sides of the mat. The plait consists of one strand being passed 
alternately over and under three (twilled). The two commenc- 
ing strands, where they reach the sides, may be finally tucked 
back and upon themselves, for strengthening purposes only. 
Certain of the strands, to intensify the pattern, may be stained 
black, even when the article is intended for domestic use, i. e., not 
for sale or barter. Two thin wooden hoops (a, 0) are next prepared,
