Checking Seam Lengths

Checking that two adjoining pattern pieces are the same length, measuring at the seam (not the cut edge).

Example

Image 1

In this case, we are 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

I am starting from the waist level moving upwards.  Where the front side seam dart point B is reached, a point/line 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.
