This piece transforms rolls of paper into skeins, with the ends split into narrow strips and spun using a drop-spindle. The word "to ply" derives from the Latin "plicare," meaning to travel back and forth along the same path, like a skein of thread plied back on itself. The title relates to the ancient writing format Boustrephedon in which the text was worked back and forth, left to right and back again, as the oxen plow the fields.
