Drafting Women's Bodice Back Sloper


[Pic of women's bodice back pattern draft.]
Draw a line equal to ( B1 / 2 ) (full width of back / 2) and mark points A and 1 .
From point 1 on line A - 1 , square a line, any length.
From point A on line A - 1 , square a line equal to B2 (full length) and mark point 2 .
From point 2 on line 2 - A , measure off B3 (center length) and mark point 3 .
Square a short line from point 3 .
From point A on line A - 1 , measure off ( B4 / 2 ) (across back / 2) and mark point 4 .
Square a line from point 4 (so that it is parallel to line A - 2 ), any length.
Draw a line equal to B5 (slope of shoulder) from point 2 to any place on line 4 , and mark point 5 .
From point 5 on line 5 - 2 , square a short line.

Draw a line equal to ( B6 / 2 ) (across shoulders / 2) from point 3 to any place on the line squared through point 5 and mark point 6 .
Draw a line equal to B7 (shoulder width) from point 6 to any place on line A - 4 and mark point 7 .
Square a short line from point 7 .
Mark the intersection of the lines squared from points 7 and 3 as point 8 .
Draw a smoothly curved neckline from point 7 into point 3 .
Extend line 7 - 6 through point 6 for 5/8 " (1.6 cm) (This measurement is the same for all sizes.) Mark point B .

From point 5 on line 4 , measure down 4 " (10.4 cm) and mark point C . This line is part of the B9 full side length measurement. It is the same length for all sizes.
Draw a line equal to the remainder of the B9 full side length measurement from point C to any place on line 1 and mark point 9 .
Line 5 - C - 9 should equal B9 (full side length).
Draw the waistline from points 9 to 2 .
Subtract ( B11 / 2 ) (back waist / 2) from the measurement of line 9 - 2 to get measurement X .
From point 9 on line 9 - 2 , measure off X / 2 and mark point D .
Draw a line from point C through point D .
From point C on line C - D , measure off the same distance as line C - 9 and mark point E .
Draw a line equal to B10 (center side length) measurement from point E to any place on line 9 - 1 , and mark point 10 .
Draw a line from point 10 to the center back, parallel to line 1 - A, and mark point F .
Draw a smoothly shaped armscye from points B to C to 10 .


[Pic of women's bodice back pattern draft.]
On line 10 - F , find the center between point F and line 4 , and mark point 11 .
Draw a line from point 11 parallel to line F - 2 , and mark point 12 .

How to make to make the back waist dart
On each side of point 12 , measure off ( measurement X / 4 ) and mark points G and H .
Draw the dart lines from points G to 11 , and from H to 11 .
(Make line 11 - G equal in length to line 11 - H . )
Draw a smoothly shaped line from point E into point G .
NOTE: Lines E - G plus H - 2 should equal ( B11 / 2 ) (one half the back waist measurement).

How to make the back shoulder dart
Find the center of line 7 - B and mark point 13 . From point 13 , draw a short line, about 2.5 " (6.5 cm) to 2.75 " (7.2 cm) long, parallel to the armscye line B - C and mark point 14 .
On each side of point 13 , measure off one-half the distance from points B to 6 ( 5/8 " (1.6 cm) ) and mark points I and J .
Draw the dart lines from points I to 14 and from J to 14 .
NOTE: Line I - 14 must be the same length as line J - 14 . If they are not even, extend line I - 14 through point I as much as necessary to make them even. Draw a smoothly curved line from the new point I into the shoulder line.

How to cut out the back bodice pattern.
Cut out the pattern on lines 2 - 3 - 7 - J - 14 - I - B - C - 10 - E - G - 11 - H - 2 .
