Understanding Knit Material

Knit material is a popular choice for sewing projects because of its stretch and comfortable feel. It is commonly used in making clothing, such as T-shirts, dresses, and sweaters. Knit fabric is made by interlocking loops of yarn together, which creates a distinctive textured appearance. There are different types of knit materials available, each with its unique characteristics and uses.

Types of Knit Fabric

There are two main categories of knit fabric: weft knits and warp knits. Weft knits are the most common type and are created by using a single thread to form rows of loops that run across the fabric’s width. The most common weave for weft knits is jersey knit, which creates a soft and stretchy material.

On the other hand, warp knits use multiple threads to form loops that run down the length of the fabric. This creates a stronger and less stretchy material compared to weft knit fabrics. Examples of warp knit fabrics include tricot and raschel.

Other types of knit fabrics include double-knit (which has two layers), rib knit (with raised ribbed lines), and cable knit (which creates a cable pattern).

Characteristics of Knit Fabric

Knit fabric has a unique set of characteristics that make it different from woven fabrics. The most prominent feature is its stretchability, which makes it more comfortable to wear and allows for easy movement. This also makes it more forgiving when fitting clothing on different body shapes.

Another characteristic is its breathability. Knit material allows air to flow through easily, making it suitable for warmer climates or physical activities where sweat can be an issue.

Additionally, knit fabric tends to be lighter in weight compared to woven materials, making it ideal for creating comfortable everyday wear items or activewear.

Tips for Choosing Knit Material

When choosing a knit fabric for your sewing project, it is essential to consider its weight, stretch, and drape. Knit material comes in various weights, from lightweight (such as jersey) to heavyweight (like cable knit). Heavier knits are best for more structured garments, while lightweight knits are better for flowy and drapey styles.

Stretch is also an important factor to consider. Some knits have more stretch than others, so be sure to check the labels before purchasing. It is also helpful to do a stretch test by pulling the fabric in all directions to see how much it stretches and how quickly it bounces back.

Lastly, pay attention to the drape of the fabric. Drape refers to how the fabric falls or hangs when made into a garment. Some knits have a more relaxed drape, while others have a more structured drape. Consider what kind of garment you want to make and choose a knit with an appropriate drape for that style.

Sewing with Knit Fabric

Sewing with knit fabric can be intimidating, especially if you are used to working with woven materials. However, once you get the hang of it, the process is quite simple and rewarding. Here are some tips for sewing with knit fabric:

Choosing the Right Needle

One crucial step when sewing with knit fabric is using the right needle. A universal needle may work for some knits; however, it is best to use a ballpoint or stretch needle designed explicitly for knits. These needles have rounded tips that push aside the fibers of the fabric instead of piercing them, minimizing damage and creating smoother stitches.

Using Stretch Stitches

Another important tip is using appropriate stitches for knits. Straight stitches tend to break on stretchy fabrics like knit; therefore, it is best to use stitches with some give, such as the zigzag stitch or a stretch stitch. These stitches allow the fabric to stretch without breaking the thread.

Some sewing machines also have specialized stretch stitches that are perfect for knit fabrics. If your machine has these stitches, be sure to experiment with them and see which one works best for your project.

Taming Curls and Waves

One challenge that beginners face when sewing knits is dealing with curling and waving edges. Knitted fabric has a tendency to curl, making it difficult to keep the edges aligned when stitching. To avoid this, you can use a rotary cutter and cutting mat instead of scissors. This will help you achieve cleaner, straighter edges.

To prevent waves in seams, stay stitch or use stabilizing tape or fabric along the seamline before stitching. This will help keep the seam flat and prevent any stretching or puckering.

Finishing Techniques

Finishing techniques are crucial for creating professional-looking garments with knit fabric. Serger machines are often used for finishing seams in knit projects, but you can also achieve a clean finish using your regular sewing machine.

One technique is called a mock serger/overlock stitch, which mimics a ser

Understanding the Basics of Sewing with Knit Fabric

Sewing with knit fabric may seem daunting to beginners, but once you understand the basics, you’ll find it’s not as complicated as it seems. Knit fabric, also known as jersey, is a stretchy material that is commonly used for making comfortable and flexible garments such as t-shirts, dresses, and activewear. Unlike woven fabrics that have little to no stretch, knit fabric can stretch in both horizontal and vertical directions.

But because of its stretchiness, sewing with knit fabric requires different techniques and handling compared to woven fabrics. In this guide, we’ll break down the key elements of sewing with knit fabric and guide you through the process of creating your own knit garments.

Choose the Right Needle and Thread

One of the most crucial aspects of sewing with knit fabric is using the right needle and thread. Using a regular sewing needle intended for woven fabric will not work on knits as it can snag or pull on the delicate fibers. Instead, opt for a ballpoint or stretch needle specifically designed for knit fabrics. These needles have rounded tips that allow them to slip between the fibers instead of piercing through them.

As for thread, make sure to use a polyester or polyester blend thread that has some give and elasticity to match the stretchiness of your chosen knits. Cotton or all-purpose threads tend to snap when stretched, resulting in broken stitches.

The Importance of Pre-Shrinking Your Knit Fabric

Like any other type of fabric, it’s important to pre-shrink your knit material before sewing with it. Even though most manufacturers claim their knits are pre-shrunk, there may still be some residual shrinkage that can cause your finished garment to become misshapen after washing.

To prevent this from happening, wash your knit fabric using cold water on a gentle cycle and then tumble dry on low heat. You can also hand wash your knit fabric in cold water and line dry it. Once your fabric is dry, press it with a cool iron to remove any wrinkles before cutting out your pattern.

Mastering the Cutting Process

Cutting knit fabric is not as straightforward as cutting woven fabrics. Knits have a tendency to curl at the edges, making it challenging to cut precisely. To avoid this, lay your fabric flat on a cutting mat or table and use pattern weights instead of regular pins to keep the fabric in place. You can also use spray stabilizer or temporary adhesive spray to help keep the fabric from shifting.

Another important tip when cutting knits is to use a rotary cutter instead of scissors. Rotary cutters make clean and precise cuts without pulling or stretching the fabric, resulting in more accurate pieces for sewing.

Handling Stretchy Seams

Seam allowance is crucial when sewing with knits as it affects the fit and stretchiness of your garment. Most patterns designed for knits will have a recommended seam allowance of ⅜ inch or less. To ensure you have consistent seam allowances, use a clear elastic guide or adjust the width of your presser foot before sewing.

Another technique for preventing stretching while sewing is using tissue paper under your stitches. Simply place tissue paper between your layers of knit fabric and sew through it. Once you’re done stitching, gently tear off the paper from the seam.

Making Hemming Easier with Double Needles

Hemming knits can be tricky as they tend to curl up at the edges, making it difficult to get a straight stitch. Using double needles can help create professional-looking hems while providing some give for stretchy fabrics.

Double needles are special needles that have two needles attached to one shank which creates two parallel rows of stitches on the right side of your fabric. Make sure to adjust your machine’s tension and test on a scrap piece of fabric before stitching your actual hemline.

Tips for Handling Different Types of Knit Fabric

There are various types of knit fabrics available, and each one may require different handling techniques. Here are some tips on sewing with some common types of knits:

– Cotton Jersey: Usually easy to work with, cotton jersey can be sewn with a regular straight stitch. It has minimal stretch and is great for beginner sewers.
– Interlock Knit: This type of knit is thicker and has more structure compared to other knits, making it easier to sew. Use a zigzag stitch for best results.
– Rib Knit: Rib knits have more stretch in one direction compared to the other, so make sure you place your pattern pieces correctly to utilize this stretch properly.
– Sweater Knit: Much thinner than other knits, sweater knits require extra care when sewing. Use a walking foot attachment or tissue paper under the seams to prevent stretching.
