Commence by drawing lines O-E and O-F. Use the arm-hole size to produce
the sleeve, and go down from O to B one-fourth of this; A is in the
middle between O and B. Draw lines across.
From O to F is one-half of arm-hole, and from there draw a line down to K.
From B to F draw a straight line and halve it, which will be point H; and
from this last also draw a short line at right angles with the diagonal
line from H to J.
Measure the length of line B-F and take one-third of it and place it from
H to J.
Now, using J as pivot, sweep from line at top, point 4, around to the
front and the back; from B curve line past 5 to this sweep. Where the
sweep crosses line at G draw a line down to K.
Go down from B to C three-fourths of an inch, and from here measure the
length of arm to E.
Mark a point midway between B and E, which gives D, and draw a line
across.
In the middle, between the two parallel lines at back, mark a point _f_.
Now lay the square in such a position on the pattern that 5 inches will
touch point E and the long arm will touch _f_, then draw along the
bottom, from E to N, and to _f_.
[Illustration]
Begin to curve from C, past L to _f_, and curve to N.
Go in from D 1½ inch and draw the front-seam of the sleeve.
From X, where the curve strikes line B, begin to draw the under-sleeve
parallel with upper part 6 to 1.
Measure from B around the sleeve-head to C, and apply number of inches
obtained to X, and measure past 1 towards 3, the measure of arm-hole, and
2 inches more. If the upper-sleeve measures 11 inches place 11 on to X
and measure 16 inches, adding 2 inches more to line at 3 for a 16-sleeve.
Wherever point 3 is located begin to draw back arm-seam to bottom by
running straight down, curving out to 2, or as much inside of line 7 as
_f_ is outside of it.
