Weaving involves crossing two threads, the warp and the weft, one
vertical and the other horizontal, one stretched taut and the other
undulating and intertwined with the first. To produce the textile it
is necessary for these two threads to be bound, otherwise each will
remain a fragile and fluttering potentiality...if the meeting of
opposites does not take place, nothing is created, for each element
is defined by its opposite and takes its meaning from it."
