Gingham or White Muslin, 4x4 Inches.
Cotton, No. 80-100.
Needle, No. 9-11.
On a petticoat either lull or small size.
For finishing the vent in certain skirts or for the opening in the back of men's shirts.
Cut a slit 2 1/2 inches down the middle, or one-half inch to the left of the middle, of the warp of a piece of gingham or muslin 4x4 inches. Put a narrow hem down the left-hand side of the slit, sloping it to nothing at the end. On the right-hand side of the slit make a hem which will be half an inch wide its entire length. When the end of the cut is reached, fold the whole width of the right-hand side over the left-hand side. This will make a pleat in the muslin below the end of the vent (some prefer the left side folded over the right). Securely fasten down the broad hem over the narrow by a line of stitching stitches at right angles with the hemming-stitches and over the end of the slit. Make another line of stitching stitches which will slant from the end of the fold of the hem, where the other stitching stitches ended, to the hemming stitches and will form the hypothenuse of the angle made by the junction of the hemming stitches with the first line of stitching stitches. This will make a more secure finish than double parallel lines of stitching stitches.
In full-sized garments the broad hem in this placket varies from 1 inch to 1 3/4 inches in width. The length varies from 5 inches to 10 inches, according to the requirements of the garment.
Garments containing plackets of this character should be brought to the class for illustration. It is well also for the classes to make small white petticoats, gingham dress skirts or flannel skirts which will apply this principle. This first placket is so simple that application on a small garment does not need to be preceded by making the practice piece. Making the placket in paper, where the subject is discussed freely, is sufficient preparation for its utilization on the small garment. A placket is more satisfactory in the back of a petticoat than a gusset, on account of the lapping over of the material in the former.
