Is sewing interlining necessary for all sewing projects? This is a question that often pops up in the minds of both novice and experienced sewers. As a supplier of Sewing Interlining, I've had the opportunity to observe a wide range of sewing projects and understand the diverse needs of sewers. In this blog post, I'll delve into the topic, exploring the scenarios where sewing interlining is essential and those where it might not be necessary.
Understanding Sewing Interlining
Before we discuss its necessity, let's first understand what sewing interlining is. Sewing interlining is a layer of fabric that is placed between the outer fabric and the lining of a garment or other sewing project. It serves several purposes, including adding structure, stability, and body to the fabric. There are different types of interlinings available, such as Lightweight Non Woven Fusible Interfacing and Non Woven Fusible Interlining, each with its own characteristics and applications.
When Sewing Interlining is Necessary
- Structured Garments
For structured garments like blazers, jackets, and coats, sewing interlining is almost always necessary. These garments require a certain amount of stiffness and shape retention to maintain their form. Interlining helps to add body to the fabric, preventing it from sagging or wrinkling easily. For example, a tailored blazer without interlining would look limp and lack the crisp lines that are characteristic of a well-made blazer. The interlining provides the necessary support to the outer fabric, ensuring that the garment holds its shape even after multiple wears and washes. - Garments with Collars and Cuffs
Collars and cuffs are areas of a garment that are subject to a lot of wear and tear. They need to be stiff enough to stand up and maintain their shape. Sewing interlining can be used to reinforce these areas, making them more durable and resistant to deformation. A shirt collar without interlining may become floppy and lose its shape over time, while a collar with the appropriate interlining will stay crisp and neat. - Projects with Heavy Fabrics
When working with heavy fabrics such as denim or wool, interlining can help to balance the weight and drape of the fabric. Heavy fabrics can be difficult to handle and may not hang well on their own. Interlining can add a layer of stability, making the fabric easier to sew and ensuring that the finished project has a professional look. For example, in a denim skirt, interlining can help to prevent the fabric from stretching out of shape and give the skirt a more structured appearance. - Garments for Special Occasions
Garments for special occasions, such as wedding dresses or evening gowns, often require a high level of precision and quality. Sewing interlining can be used to enhance the overall look and feel of these garments. It can add a luxurious touch by providing a smooth and even surface for the outer fabric. Additionally, interlining can help to prevent the fabric from showing through, which is especially important for lightweight or sheer fabrics.
When Sewing Interlining May Not Be Necessary
- Casual and Loose-Fitting Garments
Casual and loose-fitting garments, such as t-shirts, pajamas, and some summer dresses, may not require interlining. These garments are designed to be comfortable and have a more relaxed fit. Adding interlining to these types of garments may make them feel stiff and restrict movement. For example, a simple cotton t-shirt is meant to be soft and breathable, and interlining would only detract from its comfort. - Projects with Lightweight and Delicate Fabrics
Lightweight and delicate fabrics, such as chiffon, silk, and lace, may not need interlining. These fabrics have their own unique drape and texture, and adding interlining may alter their appearance and feel. In some cases, interlining may even cause the fabric to become too stiff or bulky. For instance, a silk scarf is designed to be soft and flowing, and interlining would ruin its delicate nature. - Quick and Simple Sewing Projects
For quick and simple sewing projects, such as a small tote bag or a pillowcase, interlining may not be necessary. These projects are often made for practical purposes or as a fun DIY activity. Using interlining would add an extra step and complexity to the project, which may not be worth the effort. However, if you want to add some structure to the project, you can still choose a lightweight interlining.
Factors to Consider When Deciding Whether to Use Sewing Interlining
- Fabric Type
The type of fabric you are using is one of the most important factors to consider. As mentioned earlier, heavy fabrics may require interlining for stability, while lightweight and delicate fabrics may not. Additionally, the texture and drape of the fabric should also be taken into account. For example, a fabric with a lot of stretch may need a different type of interlining than a non-stretchy fabric. - Garment Style
The style of the garment also plays a role in determining whether to use interlining. Structured and tailored garments are more likely to require interlining, while casual and loose-fitting garments may not. Consider the overall look and feel you want to achieve with the garment and whether interlining will enhance or detract from it. - Personal Preference
Ultimately, the decision to use sewing interlining comes down to personal preference. Some sewers prefer the look and feel of garments with interlining, while others prefer a more natural and relaxed look. If you are unsure whether to use interlining, you can always try making a sample piece first to see how it affects the fabric and the overall project.
Conclusion
In conclusion, sewing interlining is not necessary for all sewing projects. It depends on a variety of factors, including the type of fabric, the style of the garment, and personal preference.
