As the straws are not generally long enough without splicing, new straws are now added by lapping them from two to three inches upon the projecting ends of the straws already woven. This makes a narrow strip of double thickness down the center running the length of the mat. The weaving now continues as before until the desired width of the mat is attained, when the third corner is turned. The remainder is woven and finished at the fourth corner as shown by steps 14 and 15.
Some weavers begin at the sides, and some few, even at the corners; but this should not be encouraged since it results in making two or more seams, where the straws lap.
Care must be taken to weave all parts of the mat equally close and keep the edges perfectly straight; otherwise the mat when finished will be lop-sided, and consequently of no value. In weaving tapering grasses like tikug, which have ends of slightly different sizes, the opposite ends of the straws should be alternated. This prevents one edge of a mat from building faster than the other.
