The teacher should first demonstrate the method of gathering and assign that portion of the lesson. When the skirts have all been gathered, she should show the pupils how to measure, pin, and baste the skirt to the belt. [Illustration: _Fig._ 16.--Sewing on the belt of the apron] LESSON XIV: APRONS OR UNDERGARMENTS--Continued _Making the bib._ SUBJECT-MATTER A 2-inch hem should be turned across one short end of the bib. This should be basted and hemmed. The bottom of the bib should be gathered, the method employed for the top of the skirt being used, and sufficient thread being left to adjust the gathers easily. PRELIMINARY PLAN If the pupils have completed the skirts and attached them to the belts, they are ready to make the bibs. They should be provided with a 2-inch marker, for use in making the hems in the top of the bibs. METHOD OF WORK The teacher should guide the pupils carefully in the making of the bibs, reviewing their knowledge of basting, hemming, and gathering. [Illustration: _Fig._ 17.--Bib and straps of apron] LESSON XV: APRONS OR UNDERGARMENTS--Continued _Making the straps._ SUBJECT-MATTER One end of one of the straps should be placed at the bottom of the bib. The edge of the strap should be pinned, basted, and sewed to the right side of the bib with a running-stitch. The other long edge of the strap should then be turned in one quarter of an inch and the side turned in one inch. The strap should then be folded through the middle for its entire length and the free side basted to the wrong side of the bib and hemmed. The remaining edges of the strap should be overhanded together. The other strap should be sewn to the other side of the bib in the same way. PRELIMINARY PLAN The bibs should have been completed before the pupils report for this lesson. METHOD OF WORK As soon as the pupils report for the lesson, the teacher should explain the method of attaching the straps to the bib and tell them how to finish the former. As they proceed with their work, she should supervise them carefully and assign the unfinished portion to be done out of class.
