How to Block Fabric

Duration

18:16 min

In garment construction and draping, fabric blocking refers to the process of manipulating the fabric's grain lines (lengthwise and crosswise) to ensure they are at a perfect 90-degree angle to each other. This is crucial for achieving a well-fitting and professional-looking garment.



Why is fabric blocking necessary?

  • Correct Grain Alignment: If the grain lines are off, the fabric can distort and stretch unevenly, leading to a poorly fitting garment. Blocking helps to straighten the grain lines and prevent this issue.

  • Improved Drape: Blocking can help to improve the drape of the fabric, making it hang more smoothly and elegantly.

  • Enhanced Pattern Accuracy: When the grain lines are properly aligned, it becomes easier to accurately cut pattern pieces and ensure that the garment pieces fit together seamlessly.

  • Professional Finish: A well-blocked garment will have a more polished and professional appearance.
