A blackboard should be divided by light-colored lines, into inch squares, using a different color for every ninth or twelfth line. A permanent blackboard may be made by marking out the squares with paint. If there is a lack of blackboard room for this, mounted blackboard-cloth may be prepared, and hung on the wall or placed on an easel. The use of the blackboard is of great assistance in impressing upon the pupils the size and form of the stitches, and in teaching the dimensions in cutting.

Drawing lessons should be given in connection with sewing; they serve not only as a means for teaching the stitches, but also assist in training the eye and the hand.

A free-hand diagram, drawn on the blackboard by the teacher, in connection with the demonstration lesson, will excite the interest and gain the attention of the pupils. The name of the lesson should be plainly written on the blackboard. The copying of the diagram by the pupils will be found very effectual in teaching the size, regularity and proportion of the stitches. After a little practice and help the pupils will be able to draw more difficult stitches, and give simple sketches of their work; thereby exercising their judgment and taste.

To aid teachers, who are not accustomed to free-hand drawing, the diagram may be marked out previous to the lesson with black crayon or a soft slate-pencil; if this is done lightly it will not be perceptible to the pupils. By following this plan the different points of the lesson can be easily illustrated, as the lesson proceeds; and it has been found more effectual than a previously completed drawing.

Figures 117 to 121 are given as simple diagrams suitable to be drawn on the blackboard. They can be easily enlarged by re-drawing them in inch squares. The lines represent the threads of the cloth. Different colored chalk should be used in representing the joining of the thread; two colors are also necessary in marking to plainly show that the stitches are crossed in the same direction.

When giving a lesson on drawing the stitches or garment, squared paper or sectional exercise books will be found helpful; children will also be interested, if allowed to draw the stitches on the blackboard.
