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.
