A-B=1/3rd seat + 1½”
A-E=Length
A-C= ¹/3rd seat
Mark point H on A-C, 1” below the midpoint of A-C.
A-H =B-I. Join H-I
Mark J such that B-J =¼ seat + 1¼”.
A-C =B-D. Join C-D
From J drop J-L perpendicular to C-D. This line intersects the line H-I at the point Q.
Mark point K, ½” below Q.
Join C-K with a deep inward curve as shown.
Mark point R such that R-J = 1¼”
Drop perpendicular from R .It meets the line H-I at the point S.
Mark point M such that S-M = 1”. Shape M-K with upward curve.
G-F= ½ leg round .Join C-F
Back
A’-B’=1/3rd seat + 1½”
A’-E’=Length
A’-C’= ¹/3rd seat
Mark point H on A’-C’, 1” below the midpoint of A’-C’.
A’-H’ =B’-I’. Join H’-I’
A’-C ‘=B’-D’ Join C’-D’
From B’ measure B’-O =¼ seat-1½”
From O drop a perpendicular to C-’D’. This line meets I’-H’ at N. Produce N-O to P such that O-P = 1½”
Join B’-P as shown in the figure..
Mark T on the line I’-H’ such that N-T =1½”
Produce D’-C’ to U such that C-’U =1½”. Join P-T-U as shown.
G’- F’ ½ leg round + ½”
Join U-F’
Right side front fly facing
Using carbon paper trace shape R-J-K-S-M-R on a sheet of paper to get the draft of the fly facing.
Left side front fly extension
It is prepared in the same way but on a folded sheet of paper keeping J-K on the fold.
Allowances
Add 1½” on R-j-B- P and tops of fly facing and fly extension for stitching casing..
Add 1½” on F-G-F’ for bottom folding.
Add ½” on all other pattern edges for seams..
If side seam is needed cut front and back of the pyjama separately and add ½” of seam allowance.
If not place the drafts of front and back side by side matching the points BB’, DD” and DD”.
