Deduct the half size of waist from this last and the remainder is taken out in darts.
From U to 12 is 2 inches.
From 12 to 9 is one-half of what is to be taken out in darts.
From 9 to 8 is always three-fourths of an inch.
From 8 to 7 is another dart.
Fix a point in the centre of the darts and draw a straight line from 1 and 2 to 6 and 5; and at right angles with waist-line draw lines from centre of dart down to the bottom. Now, one-third of the height under arm, down, fix point 3, and make 4 one-half inch more.
Draw the darts from 3 and 4 through the points, as shown, to 15 and 14.
