Figure 23 represents a long, close-fitting, single-breasted sack,
consisting of back, side-body, front and sleeve. They are all drawn by
measuring the lines, and placing the number of inches on each line as
designated by the numbers shown on the Figure. Thus, for the back draw
a straight line from O, then apply each measure as shown, and draw the
lines across at right angles with the line O. When these figures are all
located, finish by drawing the outlines.
Draw the straight line O down to the desired length for the side-body;
at 28½ apply the figures on the lines—when these are all fixed curve the
outlines.
For the front, draw the straight line down from O, and mark the number
of inches for both length and width; when these are all fixed finish the
outlines.
[Illustration: Fig. 23.]
The sleeve is drawn from O down to the required length, applying the
number of inches for length as well as width, as shown; after these have
all been found, and the line drawn at right angles with the line O, draw
the outlines. After the upper part of the sleeve has been drawn cut it
out; then locate the points for the under-sleeve, and lay the back of
upper-sleeve against the points of the back part of the under-sleeve, and
draw it like the back of upper-sleeve; fix the points in front, and lay
the upper-sleeve on and draw for the front of sleeve, then finish for
top, as shown.
