When cutting out an apron, the length of the skirt should first be measured, and to this measure 6 inches should be added for the hem and the seams. One length of the material corresponding to this length should be cut. This should be folded lengthwise through the middle. Three quarters of an inch should be measured on this fold, and the material cut from the end of the selvage to this point, in order to slope the front of the apron. When the waist measure is taken, 3 inches should be added to it (1 for the lap and 1 at each end, for finishing). This makes a strong piece at each end for the button and button-hole. Two pieces of this length and 2-1/2 inches wide should be cut lengthwise of the material for the belt. A measure should be made from the middle of the back of the waist line, over the shoulder, to a point 5 inches to the right to the centre front and on the waist line. Two pieces of the length of this measure and 4-1/2 inches wide should be cut lengthwise of the material for the shoulder straps. A piece 9 by 12 inches should be cut for the bib, the longer distance lengthwise of the material. These measurements allow one quarter of an inch for seams. PRELIMINARY PLAN Before the lesson the teacher should see if arrangements can be made to secure the use of one or two sewing-machines, so that the pupils may sew all the long seams by machine. At a previous lesson she should discuss the kinds of material suitable for the aprons. The pupils should consider whether their aprons shall be white or coloured, and whether they shall be of muslin, cambric, or gingham. Each pupil will need from 1-1/2 to 2 yards of material, according to her size. The taller ones will need 2 yards. [Illustration: _Fig._ 13.--Cutting out skirt of apron] There should be on hand a sufficient number of tape-measures, pins, and scissors, so that the pupils may proceed with the cutting of their aprons without unnecessary delay. The apron to be made is to have a skirt, with a bib and shoulder straps, in order to be a protection to the dress, the skirt, and the waist.[A] [A] If the pupils are very inexperienced and find the sewing difficult, it may be advisable to omit the bib and straps and to make the simple full-skirted apron. If a machine is not at hand to use for the long seams, the limited time may make the simpler apron necessary. This will give more time for the various steps. Lessons XIV and XV may then be omitted, Lesson XVI made more simple, and less outside work may be required. METHOD OF WORK
