Checking Seam Lengths
Checking that two adjoining pattern pieces are the same length, measuring at the seam line (not the cut edge).
Example
Image 1: Checking that the back side seam length (A to B), is the same as the front side seam length (A to B plus C to D).
Image 2: Starting from the waist level moving upwards. Where the front side seam dart point B is reached, a notch point is marked on the bodice back.
Image 3: The Bodice Front is moved so that the bodice front point C aligns with the mark previously made, and the line length C-D on the bodice front is checked against the remainder of the line length on the bodice back.
