This is a demo of the simplest method of dart manipulation which is slash and spread. If you’re to alter your block by adding design lines like I’ve done to the neckline here, you might first need to move any darts that may be in the way.
Before you begin, make at least one copy of your bodice block/sloper. Unlike with the ‘pivot method’ (explained here), you’ll be cutting and I don’t want you to destroy your original!
If, on the other hand, you came here because of the filthy-sounding post title or ’cause you’re stalking the Guitar Hero dude, go away! There’s nothing to see 🙄
EXAMPLE 1: moving the shoulder dart into the armscye.
Cut the new line to bust point. Cut one of the dart lines (legs) from the shoulder dart to the bust point and ‘close’ the dart by joining the dart legs together (use some tape). The new dart will swing open.
EXAMPLE 2: moving the shoulder dart to the neckline
You can put the dart anywhere between a seam and the bust point. You can also join the two darts into one big one. In the second example, we’re moving the dart from the shoulder seam to the neckline.
Step 1 Draw a line from bust point to a point on the neckline
Challenge Want some homework to see if you’ve got it? OK, this time, move the shoulder dart into the waist dart. Your bodice front will end up having a single dart, rather wide, in the waist seam. In the next post, I’ll show you how to go from here to making a chunky pleated neckline pattern, Vivienne Westwood-style. It’s not too difficult. In the meantime, why not experiment a little by doodling where you want the pleats to be?
