This lesson will involve running and weaving. Darning is used to fill in
a hole with thread, so as to supply the part that has been destroyed or
to strengthen a place which shows signs of weakness. A darning-ball, a
gourd, or a firm piece of cardboard should be placed under the hole. The
darn should extend one quarter of an inch beyond the edge of the
material, beginning with fine stitches in the material, making rows
running close together in one direction, then crossing these threads
with rows that run at a right angle to them. Care should be taken
alternately to pick up and drop the edge of the material around the
hole, so that no raw edges will be visible, and to weave evenly in and
out of the material and the cross threads.
