Someone was kind enough to email me these. Enjoy!
Step 1: Draw a Rectangle
A-B and C-D equal the length measurement.
A-C and B-D equal one-half the total chest measurement, plus 1/2 inch.
Step 2: Construction Lines
Divide A-C & B,D in half by drawing a vertical line, E-F.
From points A and C, measure down one quarter of the length measurement, creating points G and H. Connect points G and H, forming horizontal line, G-H. This is the front and back Width Line.
From points G and H, measure down one quarter of the length measurement plus one inch, creating points I and J, forming a horizontal line. I-J is the chest line.
Step 3: Front Neck and Shoulder
3 ½ inches to the left, and ½ inch up from C, mark K.
3 inches down from K, mark L.
2 ½ inches down from C, mark M.
Connect K to L and L to M with straight lines, forming a right angle.
Use French Curve to draw in the neck curve from K to M.
Note: I usually find it helpful to bring the curve to within ½ inch of M on line L-M, so that the neckline is squared off at the fold.
1 3/8 inches below the A-C line, draw a horizontal line.
To determine the front shoulder line, place the starting end of the ruler on K and angle it to hit the horizontal line you have just drawn at exactly the neck to shoulder measurement on the ruler. Mark N at this point and connect to point K with a straight line.
Step 4: Front Armhole
Mark O on the I-J line at the point where it crosses the E-F line. This is the base of the armhole.
To the left of H, measure half the front width measurement and mark P.
Use French Curve to connect N to P with a slight curve. Connect P to O with a larger curve.
Step 5: Side Seam
To the left of D, measure one quarter of the total waist measurement, plus ¼ inch, and mark Q.
Connect O and Q with a straight line, completing the side seam.
Step 6: Back Neck and Shoulder
Draw a horizontal line ½ above A-E.
To the right of G, measure one half of the total back width and mark BB.
3 inches up from BB, mark CC, and connect them with a vertical line.
Position the starting end of the ruler on CC and angle it up to hit the horizontal line you drew above A-E at exactly the neck to shoulder measurement. Mark AA at this point and connect with a straight line. This is the back shoulder.
Connect A to AA with a slight curve. This is the back neck.
Step 7: Complete Back Armhole
Use French Curve to connect BB to O.
Step 8: Side Seam
To the right of B, measure one quarter of the total waist measurement, minus ¼ inch. Mark EE.
Connect EE to O with a straight line, completing the side seam.
Step 9: Add Seam Allowance
Add the desired seam allowance (commercial patterns use 5/8") to all sides of your pattern except for those that will go on a fold, such as the center front.
Also, to give a little more movement room, add an additional 3/8" to each of the side seams, front and back.
