If you are just sewing, you find your clothes look unprofessional. While there can be several contributing factors, the most common reason is that it lacks structure and support.

Beginners rarely realize that a garment is not just one garment. Type of fabric. Other types of tissues support outer tissues. Since they typically hide these fabrics from view, it can confuse for novice seamstresses.

But don’t let that stop you! Here we will break down the difference between lining, interfacing, interlining, and underlining. At the end, you can tackle your projects with renewed confidence and enjoy a cleaner, more professional result.

What is liner?

Whether you are a seamstress or a new crafter, you may be familiar with garment lining.

Perhaps the best known of the four types, lining refers to the fabric that lines the inside of a garment. I often made it of smooth fabric, such as cotton and silk. Unlike interfacing, liner can only to the garment by sewing. Lining often uses a different material than the outer fabric, for a few different reasons.


Alternatively, liner can also refer to the fabric going over the fabric. Seams of a garment. It from the outside, so I considered aesthetics when choosing a lining fabric.

A type of liner named coating]is used to hide seams on the raw edge of the fabric. Unlike lining, this cannot from the outside and on seams. They make it from the same fabric as the outer fabric to ensure it . It is often purely functional and not for aesthetics.

What is it used for?

Lining can in many types of garments, and with good reason.

Aesthetic purposes

The most obvious function of liner is for decorative purposes. Since they usually make lining of smooth fabrics such as silk, it is easy to find silk fabrics that are printed with patterns to serve as beautiful embellishments.

lining patterns in coats and jackets. I usually made these decorative liners with a simple color scheme, often following the outer fabric color scheme. They also have clearer colors, so as not to draw too much attention to the liner.

Patterned They often combine liners with outer fabrics that are plain, plain. color, as with coats and jackets. Even where the liner is a solid color, we took care for aesthetic in choosing the color and quality.

Glide over other garments

Rather than being aesthetically pleasing, the functional purpose of lining is to make it easier on other garments. items of clothing to slip. This is the reason lining of silk and can in almost all coats and jackets. Silk lining in jackets helps it slide over other fabrics more easily so you can get it on or off quickly.

Extra comfort

Another less obvious function of lining is comfort.

Lining of more comfortable material than the outer fabric. For example, smooth fabrics feel better against the skin and prevent chafing with other materials. As a plus, they can provide the wearer with extra warmth.

Liners made from natural fibers also allow the skin to “breathe”, keeping the wearer cool and dry. When using lining, garment makers are free to use more durable (albeit less comfortable) fabrics as the outer layer.


For sheer and opaque fabrics, lining can add an important sense of modesty to the garment. Opaque fabric lining also provides an aesthetically pleasing color contrast between the outer fabric and inner lining color.

Improved professional finish

Lining can make a garment more professional. It can help hide seams and folds, especially in fabrics that are sheer and opaque. Without lining, garments can have a different, unpleasant shape.

Remove the lining from a garment, and it may otherwise hang around the body, creating an unflattering silhouette. Lining is also helpful for tight clothing, preventing it from bunching up and sagging in areas of tension.

What is lining

When is it used?

Lining in many garments, from skirts and pants to pockets and jackets. You are free to add liner to most garments, but when should you absolutely add it? Here are some conditions to keep in mind:

  • Will your garment cover other clothing, such as coats and jackets? Add a lining of smooth material, such as silk or cotton.
  • Is your outer fabric made of an uncomfortable material, such as tweed? Add a soft lining to make the garment comfortable against the skin.
  • Is your outer fabric made of translucent or opaque material? You can add a less opaque liner for modesty and functionality.
  • Do you need to hide seam finishes and darts? Add a liner to keep it in disguise. This is especially useful for fabrics that can make seem finishing difficult, but also for beginners who may find it difficult to finish seems properly.
  • Are you using an interlining? You may need to hide this interlining with an extra layer.
  • Does it need some color? Like Untrained housewife few people will see it, but it’s fun to add something interesting. to add to your clothes.

Difference between lining and underlining

Pros and Cons of Lining

There are many advantages to feeding a fabric, from functional purposes for more aesthetic, decorative purposes. The only drawback is when garments for higher temperatures.

As a side note, it can also take a little longer to finish a garment if you want to add lining. While lining can help you finish your seams, saving you time, it can be a hassle if you’re unfamiliar with the process.

What is interfacing?

Interfacing fabric is any type of material used to provide support and stability to a garment. We can categorize it depending on how it .

The first type is fusible or iron-on interlining. As the name suggests, iron-on interlining by ironing onto the back of the fabric. The second type is non-fusible or sewn-in interfacing. I intend this type to be sewn into the outer and lining fabrics.

What is it used for?

The principal purpose of interfacing is to add structure to a fabric. Think of it as a scaffolding on a building. As a scaffold, interfacing can change the shape of a garment while making the garment more durable.

Difference between interlining and interfacing

Control form

Substances often follow the shape of the body, although this shape will change depending on the properties of the body. the fabric and how it . However, the biggest change in a fabric’s structure comes from the use of interfacing. The most common example of this is collars; interfacing gives the collars their shape, keeping the fabric stiff and upright.

Gain shape

Other than To check the shape, interfacing can also check the shape of a garment. The most common example of this feature is cuffs, which reinforce them so that they do not crease or fold.

Makes clothing stronger and more durable

Interfacing is also used to make the garment last longer, increasing the durability of the garment. fabric becomes firmer and more durable. A well-known example of this feature is the waistband and buttonholes. Waistbands and buttonholes are often more likely to be damaged than the rest of the garment because they more often. Interfacing can reduce this by creating a buffer.

When is it used?

Interfacing whenever you want to add texture to your garments. We use it in parts of a garment that need reinforcement, such as collars and cuffs. Depending on the type, it must attach an intermediate layer to the garment. Check out this guide from the Sewing Directory to learn how to link interfacing to your projects.

Pros and Cons of Interfacing

Interfacing can be useful in making a garment, but not all garments need an interfacing. In fact, if you’re a beginner, it’s best to try out simpler projects before trying on clothes that need stabilization.

When used incorrectly, a stabilizer can make a garment unnecessarily stiff, and therefore uncomfortable for the wearer. Even if a garment fares better with stabilizer, it’s difficult to apply.

Iron-on stabilizer may seem easier than its counterpart to sew on, but you have to be careful to avoid wrinkles when applying. It’s best to practice with waste before attaching it to a finished garment.

Interlining fabric

What is interlining?

When the liner is behind the outermost layer of a garment, the interlining between the liner and the outer fabric. It often goes unnoticed, unless the seamstress applies it to his own clothes. Unlike lining, interlining can sometimes . In fact, it from the garment and attached to the final product.

While the liner with smooth fabrics such as silk and cotton, interlining fabric rigid materials used such as canvas flannel and non-woven fabric. In fact, they can sometimes make interlining with interfacing. Intermediate fabric can therefore be a type of interlining when sandwiched between two other fabrics in a garment. Therefore interfacing and interlining interchangeably.

The difference between interlining and interfacing depends on how it . Interlining technically refers to any type of fabric between the outer and lining fabric – of interfacing or not. Someone often used specifically interfacing to refer to the woven fabric that makes garments more sturdy.

What is it used for?

The major purpose of Interlining is to impart heat to the wearer. That is why some tailors make the interlining removable so that the garment is more versatile, making it functional in both cold and warmer temperatures.

When is it used?

Interlining in jackets, coats and vests. To add interlining to your garments, take the pattern of your garment and cut out key pieces your intermediary. Then baste them onto your main fabric following the construction of the main pattern. While sewing, cut the interlining of your seams to reduce bulk.

What is Underline?

Similar to interlining, underlining between two fabric layers. However, unlike interlining, underlining to be removable. It is part of the garment itself, and the garment is incomplete without it. For this reason, we often find underlining throughout the garment (as opposed to interlining, which is only found in some areas). This is the major difference between underline and underline.

Lace on a lining fabric, for example. Both fabrics as one fabric and used to make a garment. Think of underlining as the equivalent of batting in a quilting project.

What is it used for?

There are two primary purposes for underlining: the first is for warmth and the second is to change the appearance of the outer fabric.


Like interlining, underlining is often used to add warmth to a garment. Someone often underline thin and sheer fabrics on the outside with thicker fabrics, so they can keep more heat and keep the wearer comfortable.

Changing Drape and Shape

Another purpose of underlining is to change the structure of the outer fabric. Adding an underline can drape the fabric or make it appear firmer. It gives more body to the outer layer, making it behave on the body.


Disadvantages of Underline

Underline can be important for many types of garments, especially those in which opaque, translucent or delicate substances .

However, consider the outer fabric you are using. Outer fabrics can be bulky and stiff on their own. Adding an underline to these fabrics can make them unnecessarily thick, not to mention overly warm. When using stiff fabrics like tweed, think twice before adding an underline.


Lining, reinforcement, interlining and underlining, all refer to fabrics used to add structure to a garment. to add. The differences between them can be subtle and confusing, but they all have their own functions – and they are all equally important to any seamstress.
