The students sample willshow the manner in which the weft threads are returnedat the edges, the cloth making what is termed the sel-vage. In the actual process of construction the warpthreads are maintained in a more or less tense condition,so that they are taken into the web of the cloth appa-rently in a straight line. But this is not actually so, asthere is always more or less deflection into a more or lesswaved form, according to the thickness of the weft threadheing inserted, and the degree of tension upon the similar deflection occurs in the weft threads, and when.

At the option of the weaver, and accordingto requirement, this flexure may be thrown into eitherthe warp or weft threads. In the section given in thefigure it is shown in the weft threads. The design of this plain weave cloth, placed upon what is termed point or design paper, would appear very much like the squares of a chess-board. It is shown in fig. 24. Let it be assumed that the warp threads are white, and the weft threads black, and that the former run in a vertical direction, and the latter in a horizontal one. In the intersection of the threads which this represents the white squares show where a warp thread is uppermost, and the black squares where the weft ?DIDIDHDDIDgoiDI?DBDBnBO??DBCBG*SDBDBGHD ?OAQBOHQ Fig. 24.
