What is Sew-In Interfacing?

Sew-in interfacing is an important tool in the world of sewing. It is a layer of material that is placed between the fabric and lining of a garment to provide support, structure, and stability. Interfacing can be made from a variety of materials such as cotton, polyester, or even fusible adhesive. It comes in different weights or thicknesses depending on the level of support needed for the fabric.

Interfacing also adds extra weight to fabrics such as lightweight silks or jerseys, giving them more body and making them easier to work with. It can prevent fabrics from stretching while being worked on, making it essential for projects such as button-down shirts or jackets.

Types of Sew-In Interfacing

There are several types of sew-in interfacing available in the market. The most common ones include woven interfacing, non-woven interfacing, knit interfacing, and sheer interfacing.

Woven interfacing is made from woven fibers and is known for its durability. It provides excellent structure to garments such as jackets and coats without causing stiffness. Non-woven interfacing is made from pressed fibers and does not have any grainline like woven interfacing. This type of interfacing offers more flexibility to the fabric while providing decent structure.

Knit interfacing is made from knit fibers and has stretch properties which make it ideal for use with stretchy fabrics. They are commonly used in knitwear such as t-shirts or activewear. Sheer interfacing, also known as organza, has a translucent appearance and adds minimal support while still keeping the fabric’s drape intact. It is often used in delicate fabrics such as chiffon or lace.

How To Choose The Right Interfacing?

Choosing the right sew-in interfacing depends on factors like fabric type, project requirements, and personal preference. To determine the appropriate interfacing for your project, consider the weight and stretch of your fabric. Heavier fabrics require a sturdier interfacing, while lighter ones may only need minimal support.

Additionally, consider the desired outcome of your project. Do you want a structured or more flowy look? This will help you determine the type of interfacing to use. It is also important to note that some fabrics cannot be ironed on, so sew-in interfacing would be the only option.

Another crucial factor to consider is the level of firmness needed for your project. If you want a garment with more body and structure, choose an interfacing with higher thickness or weight. On the other hand, if you want a softer and more flexible outcome, opt for lightweight or sheer interfacing.

How To Prepare The Fabric For Interfacing?

Properly preparing the fabric before attaching interfacing is essential as it affects the overall outcome of the project. Before cutting out pattern pieces from your fabric, make sure to prewash them according to its specific care instructions. This will prevent any shrinkage or change in shape after attaching interfacing.

After prewashing, iron out any wrinkles in the fabric using steam or spray starch if needed. Then lay out your fabric on a clean flat surface and align it with its grainline markings. The grainline indicates the direction of threads in woven fabrics and should match up with that of your pattern pieces.

Once aligned, take your pattern pieces and pin them accurately to avoid any shifting while cutting out. Cut out your pattern pieces following either a single layer or double layer cutting method depending on your preference.

How To Attach Sew-In Interfacing?

Attaching sew-in interfacing is relatively simple but requires patience and precision for optimal results.

Start by placing your cut-out interfacing pieces on top of the wrong side (non-visible) of your fabric. Make sure to match up the edges accurately with the fabric. Then, using an iron set to the correct temperature for your fabric, press gently on the right side of your fabric, melting the adhesive and attaching it to your fabric. Take care not to move or shift the interfacing while ironing.

Alternatively, you can use pins or temporary spray adhesive to hold the interfacing in place before ironing. Once attached, let it cool down and then move on to fusing the remaining pieces.

How To Sew-In Interfacing?

After attaching the interfacing, you can proceed with sewing your project as usual. It is recommended to use a slightly longer stitch length and a walking foot (if available) when sewing through both layers of fabric and interfacing. This will prevent puckering or distortion of stitches.

It is also essential to trim any excess or bulky areas of intersecting seams before turning out your project for a clean finish.

In summary, sew-in interfacing is a crucial tool in garment construction that provides structure, support, and stability to fabrics. Understanding its different types and how to choose and attach them correctly will ensure successful projects every time.

What is Sew In Interfacing?

Sew in interfacing is a popular sewing notion used to provide structure and stability to fabric projects. It is a type of fabric that is placed between two layers of fabric and then sewn into place. Its purpose is to give support, shape, and reinforcement to the fabric, making it easier to work with and enhancing the overall quality of the finished product.

There are many types of interfacing available on the market, including sew-in interfacing, fusible interfacing, and adhesive backed interfacing. Sew in interfacing is unique in that it does not require heat or adhesive to attach it to fabric. Instead, it relies on stitching techniques for proper application.

Why Use Sew In Interfacing?

Sew in interfacing has numerous benefits that make it a popular choice for different sewing projects. Here are some reasons why you should consider using sew in interfacing:

• Structure: Sewing projects often require a certain level of structure and stability. By using sew in interfacing, you can achieve the desired level of stiffness without adding bulkiness or changing the drape of your fabric.

• Versatility: One of the main advantages of sew in interfacing is its versatility. It can be used on various types of fabrics such as cotton, silk, linen, denim, wool, and more.

• Durability: Another significant benefit of using sew in interfacing is its durability. Unlike fusible or adhesive backed interfacing that may peel off after repeated washing or dry cleaning, sew-in interfacing stays securely in place.

• Professional Finish: By using high-quality sew-in interfacing, you can achieve a professional finish on your sewing projects. It helps prevent wrinkling or puckering around seams and gives a clean and crisp look to your garments.

How to Choose the Right Sew In Interfacing?

Choosing the right sew in interfacing is crucial for the success of your sewing projects. The type of interfacing you choose depends on the type of fabric, weight, and desired stiffness level. Here are some tips to help you choose the right sew-in interfacing:

• Consider fabric weight: Choose an interfacing that is suitable for the weight of your fabric. For lightweight fabrics, a lightweight interfacing will suffice. Similarly, for heavyweight fabrics, you will need a heavier or sturdier interfacing.

• Match stiffness: Decide on how stiff you want your fabric to be and match it with the appropriate level of stiffness in your sew-in interfacing. You can test this by holding up a piece of your fabric with a layer of interfacing and see if it achieves the desired level of stiffness.

• Test before use: It is always advisable to test a small piece of your chosen sew-in interfacing on a scrap piece of fabric before using it on your actual project. This way, you can make any necessary adjustments before committing to using it.

How to Use Sew In Interfacing?

Using sew in interfacing is not complicated, but it does require some sewing skills. Before starting, make sure you have all the necessary tools such as scissors, pins, marking tools, and an iron at hand. Here’s how to use sew in interfacing:

1. Prepare the Fabric: Begin by preparing your fabric pieces by pre-washing them if necessary and ironing out any wrinkles or creases.

2. Cut Out Interfacing: Place the pattern pieces facing down on top of your selected sew-in interfacing and trace around them with chalk or marking pens. Then cut out the interfacing following the pattern lines.

3. Pin Interfacing in Place: Pin the cut-out pieces of sew-in interfacing onto the wrong side of corresponding fabric pieces using more pins around edges, and fewer pins in the center.

4. Sew in Interfacing: Using a sewing machine, sew the interfacing to the fabric with a basting stitch (a long straight stitch).

5. Trim Seam Allowance: After sewing, trim the seam allowance on the interfacing side only (not on the fabric side) using pinking shears or regular scissors for a smoother finish.

6. Press Interfacing: Now it’s time to press the interfacing onto the fabric. Set your iron to a low or medium heat setting and press with gentle up-and-down movements without moving your iron back and forth. Be careful not to stretch the fabric or distort its shape.

7. Trim Fabric Edges: Once you have pressed all the interfacing pieces to their corresponding fabric pieces, trim any excess fabric sticking out from around the edges.

8. Continue sewing as usual: After applying sew-in interfacing, follow your pattern instructions as usual. Since it provides structure and support, you may need to adjust your seam allowance or needle size when sewing through multiple layers of fabrics including interfacing.
