Once weaving has reached a certain height it becomes hard to manage, so the whole tapestry is rolled on to bring the weaving point to a comfortable height again. Rolling on involves loosening both the top and bottom rollers (beams), rolling some of the completed part of the tapestry onto the bottom beam and unrolling some of the warp from the top beam, making sure that the tapestry remains level and straight the whole time. Excess weft is trimmed from the back, the cartoon is repositioned and the tension reapplied to the warp. The job needs several pairs of willing hands as can be seen from the photos.
