The teacher should begin by demonstrating on the large square of canvas
with the large needle and heavy thread the stitches to be used. After
overhanding the end of the hem, the hemming-stitch should follow with
the same thread. The pupils will probably not be able to finish the
hemming in this first lesson, so provision should be made for additional
time. This can be required as an outside assignment, if the pupils have
mastered the method during the class period. The teacher may also be
able to give them some supervision while she is looking after other
classes.
