If bias strips of silk or satin are used, the material should be cut in
strips two and one-half inches wide, on a true bias, and joined in one
long strip. Fold lengthwise through the middle and gather the raw edges
together a little less than one-quarter of an inch from the edge. This
is sewed to the frame the same as braid, the folded edge overlapping the
raw edge and the thread drawn up to adjust it as it is pinned and sewed
in place. This is an excellent way to use up old material.
