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.
