The second model in this grade is a little fancy sewing apron, which may be made of white cambric, barred mull, nainsook, or any kind of light printed goods. There are three measures taken, - a waist measure, a measure from the waist line on the left side over the shoulder and across the back to the waist line on the right side, and the length of the dress skirt less two inches.
For the skirt of the apron, take the length of the dress skirt less two inches, and cut it thirty inches wide. For the band at the waist, cut a strip lengthwise of the goods, one inch longer than the waist measure, and four and one-half inches wide. The one inch is added to the waist measure to allow for the lap. Cut the shoulder pieces also lengthwise of the goods, two and one-half inches wide, and as long as the measure.
Cut the ruffles one inch wide for the shoulder pieces, allowing half . as much more than the length for the fullness. After gathering these ruffles, and laying the gathers, baste them on either side of the shoulder pieces. Hem the ruffles on to the shoulder pieces; turn and face with a three-quarter inch bias facing. Explain that bias facing is preferable, as a rule, to straight, because it is more elastic.
Turn up the lower edge of the apron skirt in an inch-wide hem. Finish the back edges with a half-inch hem. Gather this skirt, and baste on to the waistband so that the two back edges are three inches from the ends of the band.
Sew the shoulder pieces onto the waistband with the two edges coming close together in the center of the front. Work a buttonhole in the other two ends of the shoulder pieces, cross in the back, and button an inch and a half each side of the center of the back onto the band. Finish the band with a button and buttonhole.
