Pattern Making and Blocks

When developing patterns, especially block patterns, there are several considerations to keep in mind:

• Accuracy: The grainline on the production pattern must be accurate. Any errors can transfer to the marker and cause significant issues in the garment production process.

• Block Pattern: This is a proven pattern with a good fit that has been well received by customers. It serves as a base for creating new styles, including any necessary adjustments for fabric differences, seam allowances, or shrinkage.

• Classification and Labeling: All block patterns should be clearly classified and labeled to avoid confusion. For example, a pattern that works well with knit fabric will not necessarily work for woven fabric due to differences in fabric structure and stretch properties.

• Master Block Pattern: For styles that perform well in the market, it is advisable to save the pattern as a master block pattern. This pattern should not include seam allowances or shrinkage adjustments, making it a valuable base for future style variations.

Sloper vs. Block Pattern

• Sloper: Often confused with block patterns, a sloper is a generic pattern draft based on specific body measurements. It serves as the foundation for creating a basic bodice, skirt, or pants and does not include seam allowances, ease, or fabric shrinkage. Slopers are commonly used in educational settings as a learning tool for pattern drafting.

• Block Pattern: Unlike a sloper, a block pattern is a finalized pattern that has been tested for fit and is ready for use in commercial garment production.

Conclusion

Understanding and mastering block patterns is essential for creating well-fitted garments and ensuring the success of a clothing line. As the apparel industry evolves, incorporating advanced technologies like 3D CAD systems will further enhance pattern accuracy and efficiency. Whether you are a start-up brand or an established manufacturer, investing in well-engineered block patterns will contribute to your brand's recognition and overall success.
