Pattern Drafting
Pattern construction is the foundation of fashion design, as it transforms ideas and measurements into wearable garments. It involves creating templates, known as patterns, which guide the cutting and assembling of fabric to ensure accuracy, fit, and style.
In this course/module, you will learn:
The importance of precise measurements and how they affect the garment’s fit.
Different types of patterns, including basic, block, and drafted patterns.
Tools and equipment used in pattern making.
Techniques for drafting, modifying, and adjusting patterns to bring creative designs to life.
By mastering pattern construction, students gain the skills to create garments that are not only stylish but also perfectly tailored, laying the groundwork for success in fashion design and production.
7. Pattern grading
Pattern grading is the process of increasing or decreasing a base pattern to create different sizes while maintaining the garment’s original style, proportions, and fit. It is an essential technique in garment production, especially in ready-to-wear and mass manufacturing.
Importance of Pattern Grading
Produces garments in multiple sizes (e.g., S, M, L, XL)
Maintains consistent design proportions
Saves time in production
Ensures size standardization in the fashion industry
Basic Principles of Pattern Grading
Use a Base Size (Master Pattern)
Grading begins with a well-fitting base pattern, usually in a medium or standard size.
Apply Grade Rules
Grade rules are specific measurements added or reduced at key points such as:
Bust
Waist
Hip
Shoulder
Armhole
Maintain Proportions
Adjustments must be evenly distributed to maintain garment balance and shape.
Methods of Pattern Grading
1. Manual Grading
Done using rulers and grading increments on paper.
Involves marking measurement increases or decreases at specific points.
Common in small-scale production and learning institutions.
2. Pattern Shifting Method
The pattern is moved horizontally and vertically by specific increments.
Ensures even enlargement or reduction.
3. Computer-Aided Grading (CAD)
Uses specialized pattern-making software.
Common in industrial and large-scale production.
Ensures high accuracy and efficiency.
Grading Increments
Grading increments vary depending on size charts. For example:
Bust may increase by 2–4 cm per size.
Waist may increase by 2–3 cm per size.
Hip may increase by 2–4 cm per size.
These increments must follow standard size specifications.
Guidelines for Accurate Grading
Start with an accurate master pattern.
Follow standard size charts.
Apply increments consistently at all grading points.
Re-check balance and seam lengths after grading.
