-<align justify><fs medium>Kenzo Unno has developed two basic fabric formwork methods, the Frame method (Figures 1 and 2) and the Quilt-Point method (Figures 3 and 4).  With the frame method the net fabric is stretched over the inside surface of a braced stud wall and secured with standard form ties.  The wall is vibrated externally, here by poking it with a stick.  With the Quilt-Point the net fabric is secured around the perimeter and standard form ties with washers are used to tie the two layers of fabric together assuming this quilt-like wall finish is desired on both sides.  Again the wall is vibrated externally.</fs></align>
