Drafting a Back Bodice Sloper
Using the measurements taken from the dress form, the back bodice sloper is drawn according to the following diagram. The drawing to fit the BJD will be made, step-by-step. There are about 31 steps to drafting the back bodice sloper, in Modern Pattern Design by Harriet Pepin (1942).

Read each step carefully!
6. 2-5 -- From point 2, measure off a distance on this guide line equal to one-half the Full Bodice Width Measurement. Label this point 5.
7. Square guide lines extending downward from points 3, 4 and 5.
8. B-6 -- Starting at point B, measure a diagonal line which will fall somewhere on guide line 4 which is equal to the Shoulder Pitch Measurement. Label this point 6.
9. 6-7 -- From point 6, measure a line equal to the Shoulder Width Measurement to a point located somewhere on the line 2-3. Label this point 7.
10. A-8 -- From point A, measure a line equal to one-half the Back Neck Measurement, less 1/8 inch to a point somewhere on the line 2-3. Mark this point 8. The remaining distance between points 8 and 7 represents the amount to be used for the control dart for the curve of the shoulders. Because a curved line will be made to substitute for the guide neckline 8-A, the 1/8 inch is deducted to make allowance for that fact. Since Aalish is a 1/3 scale BJD, the 1/8 inch mentioned above is about one third of 1/8 inch, or 1.5 mm
11. 6-C -- From point 6, measure downward 4 inches to a point somewhere on guide line 3. Label this point C. Connect points 6 and C with a straight guide line.
