A flat pattern is a pattern drafted on paper using measurements and geometric principles, as opposed to draping fabric on a form.
The Flat Pattern Method
Flat pattern work starts from basic blocks - simple fitted patterns with no style lines. Through slash-and-spread, pivoting, and added seam lines, the pattern maker manipulates darts, creates style lines, adds fullness, and shapes the design exactly as sketched. Every change is measurable and repeatable.
Flat Pattern vs Draping
Flat pattern is precise, repeatable, and ideal for tailored or structured garments. Draping is sculptural and intuitive, better for fluid, complex shapes. Most professional pattern makers learn both and choose per design - many garments use a combination.
Essential Tools
