Understanding the Shoulder Seam in Knitting

The shoulder seam is a crucial element in knitting garments. It connects the front and back sections of a sweater, cardigan, or other knitwear at the top of the shoulders. It provides structure and stability to the garment and ensures a proper fit on the body. A well-executed shoulder seam can make all the difference in the final look and feel of a knitted piece.

In this guide, we will focus on how to sew a shoulder seam in knitting. We will cover different methods, tips, and techniques to help you achieve a professional finish every time.

The Importance of Properly Sewing A Shoulder Seam

Sewing a shoulder seam might seem like a small detail, but it plays a significant role in how your finished garment looks and fits. A poorly sewn shoulder seam can result in an ill-fitting sweater, with one side drooping lower than the other or gaps at the neckline. It can also cause discomfort by rubbing against your skin.

On the other hand, a well-sewn shoulder seam adds stability to your garment, ensuring it retains its shape even after numerous wears and washes. It also makes sure that both sides of your sweater or cardigan sit symmetrically on your shoulders, creating a polished look.

Tools You Will Need

Before we dive into various methods of sewing shoulder seams in knitting, let’s quickly go through some essential tools you will need:

– Yarn: Choose a yarn that is sturdy enough to hold up as a seam but still pliable enough to weave through your knitting stitches.
– Sewing needle: Choose a needle with an eye large enough to accommodate your yarn without damaging it.
– Scissors: You’ll need scissors to cut yarn ends and trim any excess fabric from your seams.
– Measuring tape: This will come in handy for taking accurate measurements and ensuring your seam is even on both sides.
– Knitting needles: You may need a knitting needle to help pick up dropped stitches or loosen tight ones.

Methods of Sewing A Shoulder Seam

There are several methods for sewing a shoulder seam in knitting, and the right one for you will depend on your project, skill level, and personal preference. Let’s take a look at the three most common techniques:

1. Invisible/Smooth Seaming

This method is ideal for creating understated seams that blend seamlessly with the rest of your knitting stitches. It works best on flat-knitted pieces like scarves or panels that require an almost invisible seam. Here’s how to do it:

Step 1: After binding off your last row, leave a long tail (approximately three times the length of your seam) and thread it into a blunt-tipped sewing needle.

Step 2: Hold your two knitting pieces together with the right side facing each other. Align the edges of your work to make sure they match up perfectly.

Step 3: Insert your needle under one stitch from the front piece and then go through the same stitch on the back piece from left to right.

Step 4: Repeat this step by picking up one stitch from each side until you reach the end of your seam. End by weaving in and securing any remaining yarn tails.

2. Mattress Stitching

Mattress stitching is a popular method used to sew side seams together but can also be used for shoulder seams. It creates a neat, invisible join between two pieces of knitting fabric. Here’s how:

Step 1: Thread your sewing needle with yarn, leaving about six inches at one end (this will be used later for seaming).

Step 2: With right sides facing each other, align the edges of your knitting pieces along the row ends.

Step 3: Insert your needle under the corner stitch of the front piece and then take it through the corner stitch of the back piece creating a diagonal stitch.

Step 4: Continue making diagonal stitches from side to side until you reach the other end of your seam.

Step 5: Pull both yarn tails on each end of your work to tighten any looseness in your stitching.

Step 6: Weave in the ends of your yarn, and you now have a seamless shoulder seam.

3. Backstitch Seam

The backstitch seam is a popular method for joining pieces with different types of stitches, such as stockinette, garter, and ribbing. It creates a sturdy yet visible seam that adds a decorative touch to your project. Here’s how to do it:

Step 1: With right sides facing together, align the edges of your knitting pieces along the row ends.

Step 2: Insert your needle from behind through both layers of fabric and one stitch from the first edge (top or bottom).

Step 3: Bring your needle out at one stitch directly across on the other edge (top or bottom), making sure to keep both edges lined up.

Step 4

Preparing the Materials and Tools

To sew a shoulder seam in knitting, you will need to gather some essential materials and tools. These include a yarn needle, scissors, stitch markers, and of course, the knitted pieces that you want to join together. It is crucial to ensure that both pieces have the same number of stitches and rows before attempting to sew them together. You can use measuring tape or a ruler to double-check the measurements.

Choosing the Right Sewing Technique

When it comes to sewing a shoulder seam in knitting, there are two main techniques that you can choose from: mattress stitch or backstitch. Mattress stitch involves using a needle and yarn to whipstitch the edges of two pieces together. This technique creates an almost invisible seam, making it perfect for joining smooth knitted pieces like stockinette stitch. On the other hand, backstitch involves weaving the needle in an over-and-under pattern through two pieces of knitting to create a more visible seam. This technique works well when joining bulky or textured knitted pieces.

Selecting the Appropriate Yarn

To achieve a professional-looking shoulder seam in knitting, choosing the right yarn is essential. You want to make sure that the yarn you use for seaming matches or complements your knitting project’s overall color scheme. It is also crucial to select a yarn with good strength as it will go under tension when sewing.

Understanding Knitting Terminology

Before diving into sewing a shoulder seam in knitting, it is crucial to familiarize yourself with some basic knitting terminology. Words like “right side,” “wrong side,” “selvedge,” and “seam allowance” are commonly used in knitting patterns and can be helpful when it comes time for seaming. Knowing these terms will enable you to follow instructions more accurately and produce better results.

Identifying the Shoulder Seam

The shoulder seam joins the front and back pieces of a garment at the shoulders. To identify the shoulder seam in your knitting project, look for the section where there are no increases or decreases on either side. Another way to spot it is by locating where your stitch pattern changes direction or going from knit stitches to purl stitches.

Pinning and Securing the Pieces

To make sewing a shoulder seam in knitting more manageable, you can use stitch markers or pins to hold your pieces together temporarily. Place a marker or pin approximately an inch away from the edge of each piece at both ends of the shoulder seam. This method will keep your pieces aligned and prevent them from shifting while sewing.

Beginning the Seaming Process

Starting with one end of the shoulder seam, thread your yarn needle with a length of yarn that is approximately four times longer than your shoulder’s length. Insert your needle underneath both pieces’ first stitch at a 45-degree angle and pull it through. Repeat this step for every stitch, making sure to maintain an even tension.

Using Mattress Stitch

If you have chosen to use mattress stitch for seaming, continue sewing by inserting the needle through both pieces’ next horizontal bar. Then bring it back up through both pieces’ corresponding loops at an angle and pull it tight. Continue working in this manner until you reach the last stitch of the seam.

Switching to Backstitch

If you have opted for backstitch, once you reach your first stitch’s end, make an over-and-under motion between both pieces with your needle. Continue working in this manner until you reach the last stitch of the seam, then secure it by weaving through several stitches on either side before knotting off.

Making Adjustments as Needed

After sewing the entire shoulder seam, it is essential to check for any inconsistencies or mistakes. If needed, you can unravel your stitches and rework sections to achieve a neater look. Once you are satisfied with the seam, knot off your yarn on the inside of your garment and weave in any loose ends.

Finishing Touches

To give your shoulder seam a more polished appearance, steam block it by lightly pressing over it with a steam iron on a low heat setting. This step will help flatten any bumps or unevenness caused by sewing. You can also add decorative elements like buttons or embroidery to cover up the seam’s visible stitches, giving your creation a unique touch.

Learning how to sew a shoulder seam in knitting may seem daunting at first, but with practice and patience, you can achieve professional-looking results. Remember to choose the right technique and yarn for your project, familiarize yourself with relevant knitting terminology, and make necessary adjustments along the way. With these tips in mind, you will soon be able to create seamless shoulder seams that enhance the overall appearance of your knitted garments.
