Step 1: Identifying Pattern Markers:
Paper patterns include various labels (such as size, style number, and cut instructions) alongside practical alignment markers for sewing.
Step 2: Defining Notches:
Notches are small, precise marks (typically cut out as small wedges, or marked as small slits) on the outer edge of a pattern's seam allowance.
Step 3: Purpose of Notches in Sewing:
During garment construction, notches act as matching registration points:
- The sewist aligns matching notches on adjacent panels (e.g., matching a single notch on a sleeve to the front armhole, or double notches to the back armhole).
- This ensures that curved or long seams are joined evenly, preventing one side from being stretched or misaligned during sewing.
