How To Knit A Round Neck Cardigan?

To knit a round neck cardigan, you can follow these general steps:

  1. Choose a Pattern: Look for a knitting pattern that includes instructions for a round neck cardigan. You can find free patterns online or in knitting books and magazines. Websites like Sarah Maker offer a collection of free and easy cardigan knitting patterns6.
  2. Gather Materials: Once you have a pattern, gather the necessary materials. This typically includes yarn in your desired color and weight, knitting needles (circular or straight, depending on the pattern), stitch markers, and a tapestry needle for finishing.
  3. Read and Understand the Pattern: Carefully read through the pattern instructions to familiarize yourself with the techniques and stitches involved. Pay attention to any specific instructions for the round neck shaping.
  4. Cast On: Start by casting on the required number of stitches indicated in the pattern. This will form the base of your cardigan.
  5. Knit the Body: Follow the pattern instructions to knit the body of the cardigan. This may involve working in stockinette stitch, ribbing, or other stitch patterns. Continue knitting until you reach the desired length for the body.
  6. Shape the Neck: When you reach the point where the neck shaping begins, follow the pattern instructions to shape the round neck. This may involve decreasing stitches gradually to create the curved neckline. You can find video tutorials on platforms like YouTube that demonstrate how to decrease a round neck in a cardigan2.
  7. Knit the Sleeves: Depending on the pattern, you may need to knit the sleeves separately or in the round. If knitting in the round, you’ll need circular needles or double-pointed needles. Follow the pattern instructions to knit the sleeves to the desired length.
  8. Finishing: Once you have completed all the necessary pieces (body and sleeves), it’s time to assemble the cardigan. This may involve seaming the pieces together using a tapestry needle or joining them using a technique called mattress stitch. Follow the pattern instructions for finishing details such as adding buttons, ribbing, or edging.

Materials and Tools

When it comes to knitting a round neck cardigan, there are a few essential materials and tools you’ll need to get started. Let’s take a closer look at each one:


The first item on your list is yarn. When choosing yarn for your cardigan, there are a few factors to consider. Think about the fiber content you prefer – whether it’s wool, cotton, acrylic, or a blend. Each fiber has its own unique qualities, so consider what you want from your finished garment.

Knitting Needles

Next up, you’ll need a pair of knitting needles. The size of the needles will depend on the thickness, or weight, of your chosen yarn. It’s important to check the recommended needle size for your pattern to ensure your stitches will come out just right.

Stitch Markers

Stitch markers are handy tools that can help you keep track of specific sections of your knitting. They can be especially useful when working on the ribbing, body, or sleeves of your cardigan. These small markers will help you stay organized and avoid any confusion.

Tapestry Needle

A tapestry needle is an essential tool for finishing your knitting projects. It’s used for weaving in loose ends and seaming pieces together. Choose a needle with a large eye that can accommodate your yarn for easy and efficient finishing touches.


Lastly, don’t forget about buttons! Buttons are not only functional but also add a touch of creativity and personality to your cardigan. Choose buttons that complement your yarn color and style. Whether you go for classic, colorful, or quirky, buttons can be a delightful detail.

Now that we have our materials ready, let’s dive deeper into each step of knitting a round neck cardigan.

Choosing the Yarn

The first step in knitting a round neck cardigan is selecting the perfect yarn. Consider the following factors to help you choose:

Consider the Fiber Content

Think about the wearability, drape, and care instructions you desire for your cardigan. Wool yarns are warm and have excellent elasticity, while cotton yarns are breathable and easy to care for. There are also synthetic fibers like acrylic that offer durability and affordability. Consider your preferences and make sure the fiber content matches your needs.

Choose the Right Weight

The weight of the yarn refers to its thickness. Depending on your pattern, you may need a specific weight. For a round neck cardigan, medium-weight yarn, commonly known as worsted weight, is a popular choice. It strikes a balance between warmth and versatility for a cozy yet manageable cardigan.

Pick the Desired Color

The color of your yarn is an essential aspect of your cardigan’s overall appearance. Consider your personal style, the occasion you’re knitting for, and any existing wardrobe pieces you want to pair it with. Do you want a solid color or a variegated one? Keep in mind that knitting with lighter colors may show stitch details more prominently, while darker colors can provide a sophisticated look.

Selecting the perfect yarn is the first step in creating a cardigan that reflects your style and suits your needs. Once you have your yarn, it’s time to move on to selecting the knitting needles.

Selecting the Knitting Needles

The knitting needles you choose will play a significant role in the success of your cardigan project. Take the following factors into account before making your decision:

Check the Recommended Needle Size

Your chosen pattern will usually recommend a specific needle size to achieve the desired gauge. Gauge refers to the number of stitches and rows per inch that you should aim for. Matching the recommended gauge is crucial to ensure the right fit and dimensions of your cardigan.

Consider the Material

Knitting needles come in various materials, each with its own unique qualities. Common options include bamboo, wood, metal, and plastic. Some knitters prefer the warmth and flexibility of bamboo or wood, while others prefer the smoothness and speed of metal or plastic. Select the material that feels most comfortable to you and complements your knitting style.

Choose the Right Length

Knitting needles come in different lengths, ranging from short to long. The length you choose depends on your personal preference and the size of your project. Longer needles are helpful for accommodating a larger number of stitches, while shorter needles can make small projects more manageable. Consider the length that will allow you to comfortably work your cardigan stitches.

Now that you have your yarn and knitting needles ready, it’s time to start knitting your round neck cardigan. But before jumping straight into the project, let’s talk about the importance of knitting a gauge swatch.

Gauge Swatch

Working a gauge swatch is a crucial step in any knitting project, including your round neck cardigan. Here’s why it’s important and how to do it:

Importance of Gauge

Gauge determines the size, fit, and overall look of your finished cardigan. It ensures that your stitches are the correct size and allows you to replicate the pattern’s measurements accurately. By working a gauge swatch, you can adjust your knitting to achieve the same gauge as recommended in the pattern – ultimately resulting in a well-fitting cardigan.

Choosing the Stitch Pattern

When working your gauge swatch, choose a stitch pattern that resembles the main pattern you’ll use for your cardigan. It should reflect the complexity and texture of the stitches, giving you a realistic gauge measurement.

Working the Swatch

To work a gauge swatch, cast on a few more stitches than the recommended gauge measurement and knit a square or rectangle using your chosen stitch pattern. Make sure to knit with the same yarn and needles you plan to use for your cardigan. Measure the swatch, counting the number of stitches and rows within a 4-inch square, both horizontally and vertically.

Measuring and Adjusting

Compare your swatch measurements with the recommended gauge in the pattern. If your gauge is too loose (fewer stitches and rows per inch) or too tight (more stitches and rows per inch), you’ll need to adjust your needle size accordingly. Repeat the swatch process until you achieve the correct gauge. This step might require some trial and error, but it will ensure that your cardigan turns out just the way you envisioned.

Now that you’ve established your gauge, it’s time to start knitting your round neck cardigan. Let’s break down each step of the knitting process.

Cast On

The cast-on is the foundation of your cardigan. Here’s how to get started:

Determining the Stitch Count

Your pattern will typically provide you with the stitch count for the neckline or cardigan’s width. It’s crucial to read the instructions carefully to ensure your cast-on produces the correct number of stitches. Take note of any stitch multiples required for the pattern as well.

Long-Tail Cast On

One of the most common cast-on methods for a neat and sturdy edge is the long-tail cast-on. It creates a row of interlocking loops that are both flexible and strong. To perform this method, make a slipknot with a long tail of yarn, place it on your needle, and work each stitch following the pattern. The long-tail cast-on is versatile and suitable for various projects, including your round neck cardigan.

Alternatives to Long-Tail Cast On

If you prefer alternatives to the long-tail cast-on or need additional stitches for specific pattern features, there are numerous other cast-on methods to explore. The cable cast-on, knitted cast-on, or the backward loop cast-on are just a few options. Each method offers unique characteristics and can be a great fit for specific knitting techniques or stitch patterns.

Once the cast-on is complete, you’re ready to move on to the ribbing section of your round neck cardigan.


The ribbing section adds elasticity and structure to your cardigan’s edges. Here’s how to get started:

Starting the Ribbing Section

After the cast-on, begin the ribbing section according to your pattern instructions. Ribbing typically involves alternating knit and purl stitches to create a stretchy and textured fabric. It adds a visually appealing border to your cardigan, making it look polished and finished.

Choosing the Ribbing Stitch

There are various ribbing stitch patterns to choose from, such as 1×1 ribbing (alternating knit and purl stitches), 2×2 ribbing (knitting two stitches, then purling two stitches), or even more intricate combinations. Consider the overall look you want to achieve and select the ribbing stitch pattern that best suits your style and cardigan design.

Working the Ribbing Pattern

Follow your pattern instructions for the ribbing section, knitting the specified number of rows or until the desired length is reached. Make sure to maintain the integrity of the ribbing stitch pattern by knitting the knits and purling the purls. Ribbing provides a delightful texture and allows the cardigan to stay in place, ensuring a comfortable and snug fit.

Congratulations! You’ve successfully completed the ribbing section. Now it’s time to move on to the body of your round neck cardigan.

The body is where your cardigan starts to take shape. Here’s how to proceed:

Transition from Ribbing to Body

Once you’ve completed the ribbing section, follow the pattern instructions to transition smoothly into the body of your cardigan. This usually involves a change in stitch pattern or stitch count. Pay attention to any shaping instructions that may be needed to maintain the desired fit and style.

Working the Body Pattern

The body of your cardigan is where you’ll spend most of your knitting time. Follow the pattern instructions for this section, knitting or purling the specified stitches according to the chosen stitch pattern. The body pattern may be simple stockinette stitch, a textured pattern, or even a lace design, depending on your cardigan’s style.

Creating the Armholes

As you continue knitting the body, you’ll eventually reach the point where you need to create armholes. These openings will accommodate your sleeves. The pattern will provide guidelines on how many stitches to bind off or hold on stitch holders for each armhole. Ensure you follow the instructions carefully to maintain the correct shaping and symmetry.

With the body and armholes complete, let’s move on to the sleeves of your round neck cardigan.


The sleeves are an essential part of your cardigan, providing warmth and style. Here’s how to knit them:

Determining the Sleeve Length

Before casting on for the sleeves, determine the desired length. Consider factors such as personal preference, season, and the style of your cardigan. Do you want full-length sleeves, three-quarter sleeves, or short sleeves? This decision will impact the number of rows or rounds you need to knit.

Casting On Stitches

Using the same yarn and needle size as the body, cast on the number of stitches specified in the pattern for each sleeve. You can use the long-tail cast-on or an alternative method, depending on your preference. Ensure that the number of stitches matches the armhole’s stitch count to maintain symmetry.

Working the Sleeve Pattern

Follow the pattern instructions for the sleeves, knitting or purling the designated stitches according to the chosen stitch pattern. Pay attention to any shaping instructions, such as reducing or increasing stitches to create a tapered or bell shape. The sleeve pattern might closely resemble the body pattern or feature a complimentary stitch pattern for added interest.

Now that the body and sleeves of your cardigan are complete, let’s move on to shaping the neckline.

Shaping the Neckline

The neckline adds style and versatility to your round neck cardigan. Here’s how to shape and create a beautiful neckline:

Determining the Neckline Depth

Before you begin shaping, decide how deep you want your neckline to be. It could be a shallow scoop neck, a classic crew neck, or a daring V-neck – the choice is yours! Consider the finished look you want to achieve and your personal comfort.

Shaping the Neckline

To shape the neckline, follow the pattern instructions carefully. Most often, this involves binding off or decreasing stitches in a symmetrical manner on either side of the cardigan. It’s crucial to ensure that your decreases match the stitch pattern and maintain the integrity of the overall design.

Working the Collar or Facing

After shaping the neckline, you have the option to add a collar or facing. This adds stability to the neckline, prevents it from stretching, and provides a clean and polished look. Follow the pattern instructions to pick up stitches along the edge of the neckline and work the collar or facing in your desired stitch pattern.

With the neckline shaped and the collar or facing complete, it’s time to move on to the final steps of finishing your round neck cardigan.


The finishing touches bring your cardigan to life and make it wearable. Here’s what you need to do:

Seaming the Sleeves

Using your tapestry needle, sew the sleeves onto the body of the cardigan. Follow the pattern instructions for the correct placement and make sure to align the seams properly. Take your time to ensure a tidy and smooth finish.

Attaching Buttons

Buttons are not only functional but also add personality to your cardigan. Select buttons that match your style and the overall aesthetic of your cardigan. Use your tapestry needle and matching yarn to securely attach the buttons at the designated locations, ensuring they line up with the buttonholes.

Weaving in Loose Ends

Lastly, make sure to weave in any loose ends that remain from joining yarn or finishing different sections of your cardigan. Use your tapestry needle to thread the loose ends through the stitches on the wrong side of the fabric, securing them neatly. This step will leave your cardigan looking polished and professional.

With the finishing touches complete, take a step back and admire your beautiful round neck cardigan. You’ve followed each step of the process, from choosing the materials, selecting the knitting needles, and working through the intricate stitches. Your creativity and attention to detail have resulted in a unique and cozy garment that you can proudly wear or gift to a loved one.

Now that you’ve learned how to knit a round neck cardigan, the possibilities are endless. Experiment with different yarns, colors, stitch patterns, and button styles to create garments that reflect your personal style and bring joy to your knitting journey. Happy knitting!
