The pivot method of dart manipulation is even easier than slash and spread. Start by laying your master pattern over a blank sheet of pattern paper. Insert a pin through the dart tip and determine where you want your new dart to start. Mark this point on the pattern piece underneath and the master piece. In this example, I’m starting my new dart from the center neck line. So I’m going to start tracing the pattern piece from the right leg of the original dart to where I determined my new dart will start.
Now, pivot your master pattern piece until the the left dart leg has closed to the right dart leg location. Continue tracing the left side of the pattern piece, stopping at the new dart point marked on the master piece.
Before lifting the master pattern piece off the pattern paper, use a pen to mark where the pin goes through the dart tip to the new piece underneath. Lift away the the master copy and use a straight edge to draw new dart legs to the dart point.
And there it is. The pivot method of re-positioning darts.
