Manipulating Darts - Bodice Front
Bodice Front Style 30
The bodice of this garment has two diagonal parallel darts in the Center Front of the half-block.
Figure 1 shows the block being used on the left (1-Dart Block), and the pattern that will be created (Style 30) on the right.
Note: The actual pattern would need seam allowance or cutting instructions added; this has not been done here we are just covering the theory of manipulating darts.
In this example, the radius of the circle for the alternative Pivot Points is .75 inch (therefore the diameter is 1.5 inches). This is the same as Style 29, and less than used in Style 28. You could choose to make the circle radius 1-inch for this style, so that the darts are a bit further apart (the darts will be 2 inches apart). Note that the 1 inch radius used in Style 28 is the maximum you should use to place alternate Pivot Points; more than this will create distortion.
Instructions (Style-30) – Figure 1
In these instructions, color is used for emphasis, so it can be seen more easily, particularly in the current step. You will be using a hard (4H-6H pencil).
In this exercise, we will NOT be pivoting on the Bust Point. This is because we are creating parallel darts, and by it’s very nature, both darts cannot be pointing towards the same point. See the page on Complex Dart Manipulation if you have not already done so (if you click on the link, it will open in a new window).
- Draw a circle, with the Bust Point at the center, with a radius of .75 inch (2 cm). This means the diameter will be 1.5-inches, and the parallel darts will be 1.5 inches apart.
- Draw a line from one side of the circle (Pivot Point 1, where the arrow tip touches the circle) to the CF.
- Draw a parallel line to the first line, from the other side of the circle (Pivot Point #2, where the arrow tip touches the circle) to the CF.
Since the darts are parallel, the distance between the two dart lines is the same for the entire length.
Instructions (Style-30) – Figure 2
- Extend dart leg A out onto the paper for some distance.
- Trace the block in an anti-clockwise direction from the waist dart leg point A, around to the new dart line D.
- Mark the Bust Point AND both Pivot Points on the paper underneath by piercing holes through the cardboard with an awl.
Instructions (Style-30) – Figure 3
- Hold down the block at Pivot Point #1 (NOT the Bust Point), turn the block in a anti-clockwise direction and close half the waist dart. Closing half the dart means that the mid-dart point B will reach the green arrow.
- Trace the block from point D to E (in-between the two parallel dart lines).
Instructions (Style-30) – Figure 4
- Holding the block at Pivot Point #2 this time, turn the block in an anti-clockwise direction and pivot the rest of the waist dart closed; i.e. until dart leg C reaches the green arrow.
- Finish tracing the block from point E to point C.
Instructions (Style-30) – Figure 5
You can lift up the block and put it aside.
- Draw the dart legs to PP1 and PP2.
- Make sure the dart legs for each dart are the same length; some small adjustment may be required. (Pivoting on points other than the Bust Point will create some small errors).
- Blend the waistline if needed.
Instructions (Style-30) – Figure 6
- Finish off the darts, remembering that the Dart Point stops some distance before the Bust Point, and in this case even further than would be the case when the dart is pointed to the Bust Point.*
- Of course, if this was a pattern, you would need to add seam allowance, cutting instructions, grainline, label the pattern piece, etc.
