As in the preceding stitches, after counting a space of six threads of the canvas, begin the first line of hemming by taking a slanting stitch of two threads, leave one space, and take another slanting stitch. Call the attention of the pupils to the neat appearance of the even lines, stitches, and spaces, and let them, as before, start the third line without help. There is nothing more important than a standard of taste, and no opportunity should be neglected to establish a correct standard. This can be best accomplished by inciting admiration for that which is excellent.
