Pattern Drafting Process: The pattern drafting process begins with taking accurate body measurements of the wearer. These measurements typically include: bust, waist, hips, shoulder width, sleeve length, and back length. These measurements are then used to create individual pattern pieces that represent the different parts of the jacket (e.g., front panels, back panel, sleeves, collar).

Key Markings on Pattern Pieces: Pattern pieces include several essential markings:

• Grainline: A line running parallel to the selvage of the fabric. This ensures the pattern piece is laid on the fabric with the grain running correctly, preventing distortion.
• Notches: Small triangular or shaped marks used to help align pattern pieces during assembly. They indicate where pieces should be joined.
• Darts: Angled cuts used to shape the fabric to fit the body contours.
• Bridges: Connecting lines between two pattern pieces, often used for shaping or reinforcement.
• Fold Lines: Indicate where the pattern piece should be folded when laid on the fabric.
• Cutting Allowance: An extra amount of fabric added to the pattern piece to allow for seam allowances and potential errors.

Accuracy and Assembly: These markings are crucial for accurate cutting. The grainline ensures the fabric drapes correctly. Notches ensure pieces are joined in the correct order and orientation. Darts shape the garment to fit. Without these markings, the jacket would likely be ill-fitting and poorly constructed. Accurate cutting based on the pattern pieces ensures that all the necessary components are the correct shape and size for successful assembly.
