Continue How many types of dart manipulation are there To add to my Pattern Drafting for Beginners series, in this tutorial, I will focus on dart manipulation and how you can use the slash & spread or pivot method to transfer darts to the bust, neck, armhole or anywhere you want! This is a two part tutorial with the first part being specifically for beginners. The second part will be slightly more advanced but straightforward enough to follow. Dart manipulation is one of the most important techniques when it comes to pattern drafting. The shape and fit of garments depend on darts and while they are needed to help garments stay in shape, they can also be used as a design element so knowing how to move darts will be beneficial. I’ve used dart manipulation when making a lot of my dresses. For example, the gathers on the neckline of the night version of my mix and match dress came about through using dart manipulation techniques. I hope you find this tutorial useful. Part 2 is now available where I show you how to create multiple darts from a single dart! Pattern Drafting for Beginners – Dart Manipulation – Slash & Spread and Pivot Method Subscribe to my YouTube Channel Check These Out This article is about the sewing term. For other uses, see Dart (disambiguation). The reverse side of fabric showing where a dart has been taken in and stitched to tailor the shape of a garment to the wearer. Darts are folds (tucks coming to a point) and sewn into fabric to take in ease and provide shape to a garment, especially for a woman's bust. They are used frequently in all sorts of clothing to tailor the garment to the wearer's shape, or to make an innovative shape in the garment. Fabric may be thought of as flat, and a dart has the effect of removing a wedge shaped piece and pulling the edges of that wedge together to create a shallow cone. This effect can be seen quite easily with a paper pattern by pulling together the edges of a dart intake as it would be sewn. Since fabric is generally more flexible than paper the fabric will shift around the apex of the cone and form a softer, but still curved, shape. In a garment a dart ends in a point at a full area of the body. A dart in a flat pattern has two important properties: its point, the point in the pattern at which the dart aims or converges, and the intake, or the amount of fabric taken in or removed. Since the dart can extend toward any edge of the pattern without affecting fit, the length of the dart intake at the edge of the fabric is not a good measure of dart intake. Rather, the angle subtracted from the pattern by the dart is what determines the dart's intake. Manipulating darts in flat patterns As long as the focal point of a dart and its intake remain the same, a dart can be rotated around its focal point, or stylized in one of several ways without affecting the fit of the garment. Slash-and-spread dart rotation An easy way to rotate a dart on a flat pattern is to slice a straight line from the dart point to another edge of the pattern (the slash). The two pieces thus created can then be pivoted (spread) at the dart point to shift the dart to the position of the slash. Pin and pivot dart rotation The pin and pivot dart rotation technique requires tracing a new pattern from the original. First, the pattern with the dart to be rotated is set on top of another piece of paper on which the new pattern will be traced. A pin is pressed into the dart point to hold that point in place. Then one leg of the original dart and an arbitrary part of the original pattern is traced onto the paper. This tracing starts from the one dart leg and continues from there to the new point where the dart will reach the outside of the pattern piece. The pattern is then rotated around the pinned dart point until the other dart leg lines up with the traced dart leg. Tracing can then continue from the same spot on the original pattern. The pattern is then removed and the new dart legs drawn between the dart point (marked by the pin hole) and the gap in the pattern created during rotation. Dart equivalents Pleats or gathers in the fabric can be used for the same purpose as a normal stitched dart. These are called dart equivalents.[1] Darts can also be worked into style lines. Named dart styles Two kinds of darts are common in blouses for women: Vertical darts—These are sewn from the bottom of the blouse to a point generally around the bustline. This type of dart may be found in the front, rarely in the back of a garment and are used by the garment maker to pull in the bottom of the blouse towards the wearer's waist. Fisheye darts[2] Bust darts—These are short triangle folds that provide space for breasts such that the fabric under the breasts isn't hanging, rather is fitting closer to the wearer. There are several subtypes of bust line dart:[3] Center Waistline French Side seam Armhole Neckline Shoulder T-dart Inverted T-dart In the early 1950s, the New York City firm of Evan-Picone pioneered the use of darts in the pockets of women's clothing. The darts help keep the pocket open and thus more easily accessed, reducing the chance of rips or tears.[4] See also clothingat Wikipedia's sister projectsDefinitions from WiktionaryMedia from Wikimedia CommonsNews from WikinewsQuotations from WikiquoteTexts from WikisourceTextbooks from WikibooksResources from Wikiversity Princess seams References ^ Joseph-Armstrong, Helen (2010).

Home › Tips and Techniques › Manipulating Darts for Style I know, I know, darts are clunky and unattractive. But did you know you can use them to create styling details - while maintaining the great fit you worked so hard to achieve?Darts can be converted to shaping seams, which look so much better than those pointy little wedges of fabric. A princess seam, for example, is sleek and smooth. It's flattering to almost everyone - and who knew those pesky bust and waist darts are hidden in there???In this video, I give you step-by-step instructions for transforming your clunky darts into a smooth, sleek princess seam. There are many more ways you can manipulate darts to create styling details. They can be converted into pleats, at the shoulder or a center front seam. They can be incorporated into a yoke seam. They can be divided into multiple darts and moved to the neckline (either at evenly spaced darts or pleats), they can be converted into gathers - the list is almost endless!I show many other options in A Beginner's Guide to Designing with Darts.Get out your quarter scales, and start practicing dart manipulation!

So, to kick off this year I wanted to dive deeper into Pattern Darts to help you understand one of the most valuable tools in your Patternmaking Arsenal.Personally I don’t think that Darts get the attention they deserve. This concept is truly one of the most important to understand if you want to find success as a Fashion Designer.Need a refresher on the basics?

This article contains affiliate links - learn what that means for you and for me. Darts are a powerful tool of the Patternmaker to make flat fabric into 3D shapes for the garment. Therefore, understanding how darts work is a vital part of manipulating them to fit your design.What is a Dart?A pattern dart is where excess fabric is taken in on the garment. Typically, a dart is recognized by its triangular shape on the pattern piece. However, the darting of the fabric can take on other shapes.What does a Dart do?The purpose of a dart is to create the shape to accommodate the curves, contour, and volume of the body or the design.PATTERNMAKING PRINCIPLES“Darting” excess fabric to create shape follows three main principles:Dart Manipulation - How the location of a dart is changed within the pattern. A dart can be transferred to any other point around the pattern (in relation to the pivotal point - bust point) without changing the fit of the garment.Adding Fullness - Applies when the excess fullness needed is greater than that of the dart. The slash and spread technique is used to add fullness where desired.Contouring - Absorbing the dart excess into style lines to create a contoured silhouette. When developing or editing a pattern, you will need to adjust the darts to fit your desired silhouette. This means that we need to transfer the shaping (darts) to our new desired style lines. In order to do so, you will need to follow two manipulation techniques:Slash and Spread - The new design line is cut and spread open to create a new dart, while the original dart is closed. The working pattern is altered.Pivot - The pivotal point (bust point or dart point) stays stationary. The pattern is traced and pivoted to close the old dart and create the new dart. The working pattern is not altered.Follow me on YouTube for more educational videos!One area that I see often confused is how to identify the Pivotal Point. While it may seem like the Pivotal Point should be at the dart tip, in reality it is at the Bust Point (for this example pattern). Therefore, when manipulating the dart of the front bodice we must first find the Bust Point or Pivotal Point.After we have adjusted the dart, then we will have to re-establish the dart point away from the apex of the bust. It is recommended to offset the dart point 5/8” from the apex of the bust.PRO TIP: Always remember to remove seam allowance before making changes to the pattern! The dart can be moved virtually anywhere around the Pivotal Point without changing the fit of the garment. Here are some common placements for the new dart location: To use the “Slash and Spread” Technique to adjust your dart position:First choose where you would like your new dart to be located.Draw a straight line from the new dart location to the Pivotal Point.Cut this new line TO but not THROUGH the Pivotal Point (leave a small connection in the paper).Drag the separated piece to close the original dart. Tape.Mark 5/8” from the Pivotal Point in the center of your new dart. This is your new Dart Point.Connect the new Dart Point to the Dart Legs. To use the “Pivot” Technique to adjust your dart position:Place a pin through the paper at the Pivotal Point.Decide on and mark where you want your new dart.Trace from new dart position to original Dart Leg.Pivot the pattern to close the original dart.Trace from the closed Dart Leg (original) to where you marked the new dart on the pattern piece.Remove the pattern on top.Mark 5/8” from the Pivotal Point in the center of your new dart. This is your new Dart Point. Connect the new Dart Point to the Dart Legs. Thanks for reading!

In this post you will learn what dart manipulation is, the two ways darts can be manipulated and the locations of those new darts. Dart manipulation is one of the most creative ways to develop sewing patterns, or even get creative with patterns that you know and love. The female body is made up of nooks and crannies, and to create clothes that fit those nooks and crannies, we need to manipulate the fabric to be more form fitting. We use darts in sewing to suppress the fabric when we want to achieve this more fitted look. However, as well as creating a more fitted appearance, darts also work to add fullness too, which helps to create interesting clothing styles. What Is Dart Manipulation? Aha, now this is where we start getting into the nitty gritty of dart manipulation. Dart manipulation is the art of taking the existing darts in a sewing pattern, and manipulating them around the pattern to achieve something else. The actual dart manipulation definition reads (on Wikipedia): “Darts are folds and are sewn into fabric to take in ease and provide shape to a garment.” Now, that isn’t a very understandable definition of dart manipulation, so lets break it down a little more. If you image standing in front of a mirror, inside a tube of fabric. The fabric fits perfectly at the fuller areas – the hips and bust – but is baggy in other areas, such as the waist, around the chest, and below the hipline. We need to compress that fabric so that it fits closer to the body, and we do that by using darts. The manipulation of darts is most fun and creative around the women’s bust area. We often go for a tailored look, with well fitted garments, or sometimes rather fun and playful styles with cool style-lines or added fullness created by dart manipulation. What Is Added Fullness? Added fullness is the result of manipulating darts to allow more fabric in an area of the sewing pattern, which results in more fullness. A simple way to visualise it would be to think of a trapeze dress, which flares out with additional fullness. This is done using dart manipulation. Are There Types Of Dart Manipulation? Yes! When it comes to manipulating darts there are two methods that are used: Slash and spread methodPivotal method What Is The Slash and Spread Method In Pattern Making? The slash and spread method in pattern making is exactly as it sounds. Your pattern is cut (slashed) to the dart point, and then spread open the required amount to add fullness, or moved closer together to remove the fullness. You can learn more about the slash and spread method here! What Is Pivot Method? The pivot method of dart manipulation is when we move the pattern at the dart point, and trace around the pattern to remove or add fullness, instead of cutting into the pattern itself. Slash And Spread Vs Pivot Method Typically, any one new to pattern drafting and experimenting with dart manipulation would start by using the slash and spread method in pattern making. It is an easier – though longer – process that works well and allows less room for error, as you are working directly with the existing pattern pieces. Pivoting a pattern is a more advanced pattern drafting technique as there is more room for error. The number of times my awl has moved without my noticing, and I’ve ended up with something unexpected! Which Dart Manipulation Technique Should I use? If you’re new to dart manipulation, try the slash and spread first. It’s fun, and I always find that when I have taught that technique to students in person, they grasp the concept of dart manipulation much faster. I’m going to cover both in step by step tutorials further below, so don’t worry, you’ll have a chance to try both! Types Of Darts In Sewing There are only two types of darts in sewing: Single dartsDouble ended darts – also know as fisheye darts Single Darts Single darts are the ones which have one point, and two dart legs, forming a triangle of sorts. These are found all over the bodice blocks, on the sleeve, trousers and skirts too. There isn’t anywhere that you cannot put a dart, depending on what the final effect is that you are aiming for. Double Darts aka Fish Eye Darts Double darts are also known as fisheye darts. They have two end points, two wider points, and then legs that connect all points together. When seen un-sewn, they look like a fisheye. The fish-eye dart is the dart you find on the front and back sections of a fitted dress pattern, running from the bust, down towards the hip, to suppress the fabric for a closer fitting dress. What Are The Different Dart Styles? Are there different dart styles? Yes! There are 10 styles of dart on the basic front bodice. These are fixed locations that we would transfer a dart from and to: Standard waist dartFrench dartArmhole dartMid shoulder dartCentre front bust dartCentre front neck dartStraight side seam dartShoulder tip dartMid neck dartCentre front waist dart Let’s take a look at each these dart locations! Standard Waist Dart Position The standard waist dart is a vertical dart from the waistline up to the bust point. It is one of the key darts used for manipulating fabric around the bodice. The standard waist dart can be divided into two or three darts and sewn as darts, external pleats or tucks, for some style variations – we’ll cover that in a later tutorial! French Dart Position The French dart is a diagonal dart from the side seam up to the bust point. It is created by transferring the excess in the waist dart into a dart at the lower side seam – usually 2-3 inches up from the waistline. The French dart is often found on silk tops for a more ‘finished’ look. Armhole Dart Position The armhole dart is a diagonal dart from the mid armhole down towards the bust point. This is quite a popular dart, used to shape tops and blouses around the bust that then fall straight down or into a flared hem. Mid- Shoulder Dart Position The mid-shoulder runs from the middle of your shoulder, down to the bust point. You’ll often find this dart is drafted in when drafting a female bodice block. Outside of drafting blocks, this dart is often incorporating into a princess style dress! Centre Front Bust Dart Position The centre front bust dart is a horizontal dart from the centre front towards the bust point. If the pattern is cut on the fold, this dart becomes a fish-eye dart, running horizontally. This dart is often manipulated to create a little gathering on the centre front rather than an actual dart. It can also be used to create a bib or yoke effect on tops and dresses. Centre Front Neck Dart Position The centre front neck dart is a diagonal dart from the centre front down to the bust point. It is often used as part of a style-line to suppress the fabric in an interesting way. Straight Side Seam Dart Position A straight side seam is a horizontal dart from the side seam towards the bust point – the least used dart by me when I’m working on dart manipulation! I also see it very rarely in current fashion, so might be one to steer clear of! Shoulder Tip Dart Position The shoulder tip dart is a more dramatic diagonal dart from the shoulder tip, running in and down, to the bust point. Using a dart int his position is tricky, because you do end up with a very thin section of the bodice pattern next to the shoulder. that said, if you were planning a bodice with the sleeve factored in – a kimono top or batwing top! – then the shoulder tip dart will work very well! Mid-Neck Dart Position A mid-neck dart – from the middle of the neck down to the bust point – is often used to open up the neckline and add fullness in the form of gathers around the neckline. It can also be used to create front yokes and bibs on blouses or shirts. Centre Front Waist Dart Position The centre front waist dart is manipulated from the centre waist to run diagonally from the waistline at centre front, up to the bust point. You can see from the various overview images above that in the examples, the dart is drawn as a straight line on the bodice outline. As an actual dart however, the dart legs can be drawn straight or curved, depending on how much contouring is needed – we’ll cover contoured darts later on in this series. Dart Manipulation Tutorials Now that you have a thorough understanding of what dart manipulation is and the locations we move darts to, the next step is to actually start manipulating some darts. Next week I’m going to show you how to use the two techniques for manipulating darts that we looked at earlier. Slash And Spread Method This is a great dart manipulation technique for beginners who want to try manipulating darts around the bust point. Because you’re cutting the pattern, and physically moving paper around, it makes it easier to rasp the concept of dart manipulation. Pivoting Darts This technique is a little more advanced. There’s no cutting and moving of paper pattern pieces, instead we will be using an awl to manipulate the lower pattern and a pencil to trace off.
