Seams and stitches

• Double stitches are always parallel to each other and to the line of the seam.
• All stitches in double top stitching, as a rule, are aligned.
• Top stitching and seams must be depicted with a different type of line: seam as a solid line and top stitching as a dashed line.
• Industrial top stitching and handmade top stitching must be depicted differently:
  • In handmade top stitching spaces between stitches are longer than the length of the stitches themselves.
  • In industrial top stitching spaces between stitches are shorter than the length of the stitches themselves.
• Seams: side seams and shoulder seams must be equal on the front view and on the back view of the same garment.
