The teacher should have the necessary materials on hand or should see
that they are supplied by the pupils. The articles needed will include
material for the towels, white thread for basting and hemming, and
gauges for measuring.
The teacher should also have a large square of unbleached cotton or
canvas, 18 by 18 inches, and a large darning-needle and coloured worsted
thread, to use for demonstration purposes. The canvas should be fastened
to the black-board, where the class can see it easily.
