The checker weaving of the mat is now begun at the left edge by doubling the weft element over the last warp and then weaving with the doubled element over and under one warp until the right edge is reached where it is turned back and slipped under an inch of the weaving just completed. Figure 1 shows a squaw at work on such a mat, and when she has completed this half of the mat the second half will be undertaken. She finishes the edge by turning up the warp ends below the last line of weft and binds them with a row of twining just above this last weft.
