The slash and spread method is a technique for relocating darts on a pattern, specifically demonstrated here by transferring a waist dart to the side seam. This process facilitates adjustments to the garment's shape and fit. Steps:
Begin by drawing the basic bodice block with the waist dart on paper. Draw a line from the dart's apex to the waistline, outlining the dart legs. Cut along one dart leg from the waistline to the apex, leaving a small hinge at the apex. Repeat the cut along the other dart leg, also stopping at the apex. Create a new cut line from the apex extending towards the side seam, indicating the placement of the new dart. Spread the pattern by opening the original waist dart legs apart, which will cause the original dart to close. Simultaneously, close the slash cut towards the side seam. This action forms a new dart at the side seam. Trace the outline of the modified pattern and mark the newly formed side seam dart. Diagram: A labeled diagram is required, illustrating the basic bodice block with the waist dart, the cut lines (slash lines), the action of spreading the original dart, and the closing/opening of the new dart at the side seam.
