AvatarByJill Nammar Sewing

Sewing is a timeless skill that has been passed down through generations, allowing us to create our own unique pieces of clothing or home decor. While basic sewing techniques may be relatively easy to grasp, there are certain aspects that can still leave even experienced sewers scratching their heads. One such technique is sewing bias strips together. Bias strips are essential in creating beautifully finished edges and borders, but figuring out how to sew them together seamlessly can be daunting. In this article, we will delve into the world of bias strips and guide you through the steps of sewing them together like a pro. From choosing the right fabric to executing the perfect seam, get ready to master this skill and take your sewing projects to the next level.

Sewing bias strips together allows for a clean and professional finish on various sewing projects. Bias strips, also known as bias binding, are thin strips of fabric cut on the diagonal grain, providing flexibility and stretch. This technique is commonly used for finishing edges and creating durable seams. In this guide, we will dive into the step-by-step process of sewing bias strips together to achieve a perfect seam every time.

Understanding Bias Strips

Before delving into the process of sewing bias strips together, it is essential to understand what they are and how they work. As mentioned earlier, bias strips are thin strips of fabric cut at a 45-degree angle against the grain line. This angle creates stretch and allows the fabric to curve easily around corners and edges.

Bias binding can be made from any fabric, but cotton or poly-cotton blends are ideal for their durability and minimal stretch. The width of the strip can vary depending on your preference, but common sizes range from ½ inch to 2 inches.

Bias strips are widely used in garments, home décor items such as quilts and table runners, as well as in crafting projects like bags and purses. Understanding how to sew them together is crucial to achieving a professional finish.

Cutting Bias Strips

To start the process of sewing bias strips together, you must first cut the fabric into thin diagonal strips. Cutting these accurately and precisely will make a significant difference in the final product’s appearance.

Begin by laying your fabric flat on a cutting mat with the selvage edge (the finished edge) at the top. Align one corner of your fabric with one of the horizontal lines on your mat.

Take one corner at the bottom left of your fabric and fold it diagonally up towards the top edge of your fabric. The fold should create a 45-degree angle with the horizontal line beneath it.

Next, cut along the fold, creating your bias strip. If you are using a rotary cutter, a clear ruler will help ensure clean and precise cuts. Continue to cut strips until you have enough for your project.

Joining Bias Strips

After cutting all the necessary strips, it’s time to join them together. Joining bias strips is necessary when you need a longer strip than what one piece of fabric can provide. It is also useful for minimizing fabric waste.

Start by laying two strips right sides together at right angles to each other, forming an “L” shape. Align the edges and pin them in place.

Next, sew along the diagonal edge with a ¼ inch seam allowance. Trim off any excess fabric and press open the seam with an iron.

Continue this process until you have joined all your strips to create one continuous strip.

Creating Continuous Strips

If you need an extremely long strip or do not want any visible seams on your project, there is a way to create one continuous bias strip from one piece of fabric.

Start by folding one corner of your fabric diagonally towards the bottom edge like before. Instead of cutting along the fold, start cutting from one corner towards the other in a spiral shape. This creates a long continuous strip that can be used for longer projects and reduces waste.

Sewing Bias Strips Together

Now that you have your bias strip ready, it’s time to sew it onto your project. Start by unfolding one end of your strip at a 90-degree angle and lining it up on the edge of your project’s right side (the side facing up).

Using a ¼ inch seam allowance, begin sewing along the edge of the bias strip until you reach a corner or curve. To sew around corners, continue sewing until you are about ½ inch from reaching the end of the edge. Then, fold the bias strip down in the same direction as the edge and continue sewing along the next edge.

For curves, slightly stretch the bias strip to fit along the edge while sewing. This allows for a clean and smooth finish. Once you have sewn around your entire project, fold over the end of your bias strip, enclosing all raw edges, and sew down to secure it in place.

Sewing bias strips together may seem like a daunting task, but with practice and precision, it becomes a straightforward process. Remember always to cut your strips accurately, join them correctly by aligning edges at right angles, and use a ¼ inch seam allowance when sewing around curves. With these steps in mind, you can achieve a clean and professional finish on all your sewing projects using bias strips.

Understanding Bias Strips

Bias strips are essential components in many sewing projects. They are thin strips of fabric cut on a 45-degree angle from the grain of the fabric, which gives them a stretchy and flexible quality. Bias strips are often used to create bindings, piping, and other decorative elements in garments and home decor items.

To make bias strips, you will need to start with a square piece of fabric. The size of the square will depend on how wide you want your bias strips to be. As a general rule, for every inch of width you want your bias strip to be, you will need about two inches in length. For example, if you want your bias strips to be one inch wide, you will need a 2-inch square piece of fabric.

Once you have your square piece of fabric, fold it diagonally in half to create a triangle shape. Then, fold the triangle again diagonally in half. Now you have a smaller triangle shape with two folded edges and one raw edge. Carefully cut along the raw edge to create a long strip that is cut on the bias.

Preparing Bias Strips for Sewing

Once you have your bias strips cut, it is important to prepare them for sewing. Begin by pressing the strip with an iron to remove any wrinkles or creases. This will ensure that your finished project has a neat and professional look.

If your project requires multiple bias strips sewn together to make one long strip, this is where preparation becomes crucial. Take each end of two different bias strips and place them right sides together at a 90-degree angle. Sew across the corner with a straight stitch to connect the two pieces. Then trim off any excess fabric and press open the seam.

Repeat this process until all of your bias strips are connected into one continuous piece.

Sewing Bias Strips Together

Now that your bias strips are ready, it’s time to sew them together. When sewing bias strips together, it is important to use a technique called “bias seaming.” This method ensures that your finished strip will have a smooth and seamless look.

Begin by placing one bias strip on top of the other with right sides together. Make sure the edges are aligned evenly. Then take the top layer and fold it back at a 90-degree angle. Sew the two pieces together along the diagonal edge, using a ¼ inch seam allowance.

Once sewn, open up the two layers and press the seam flat. Trim off any excess fabric and repeat this process until all of your strips are connected.

Finishing Bias Strips

After sewing all of your bias strips together, you may need to finish the raw edges depending on your project. To do this, you can either use pinking shears to trim along the edge or apply an adhesive binding tape.

If you choose to use binding tape, start by aligning one edge of the tape with the raw edge of your bias strip and ironing it in place. Then fold over the tape to cover the raw edge of the strip and iron again to secure it in place.

You can also create mitered corners if your project requires them. To do this, fold one corner of your bias strip at a 45-degree angle and then fold over again at another 45-degree angle. This will create a neat and professional-looking corner.

Sewing bias strips together is an essential skill for any sewer looking to add decorative elements to their projects. By understanding how to prepare and sew bias strips correctly, you will be able to achieve a clean and polished finish every time. With practice, you can use bias strips in various ways to add unique touches to your handmade garments or home decor items. So next time you come across a pattern that requires bias strips, you can confidently sew them together and create beautiful and professional-looking finishes.

1. What are bias strips and why do I need to sew them together?
Bias strips refer to fabric strips that are cut on a diagonal grain rather than on the straight grain of the fabric. Sewing bias strips together is important because they provide stretch and flexibility, making them ideal for curved or angled areas on a garment or project.

2. How do I determine the length and width of my bias strips?
To determine the length of your bias strip, measure the distance you want to cover and add 1 inch for seam allowance. To calculate the width, multiply the desired finished width by two and add 1/2 inch for seam allowance.

3. What type of stitch should I use when sewing bias strips together?
A straight stitch or a narrow zigzag stitch is most commonly used when sewing bias strips together. It is important to use a small stitch length to ensure that the seams are secure and will not unravel easily.

4. Can I use a serger to sew my bias strips together?
Yes, you can use a serger to sew your bias strips together if you have one available. However, if you do not have access to a serger, a regular sewing machine will work just fine.

5. How do I join two ends of a bias strip together?
To join two ends of a bias strip without creating any bulk at the seam, open up one end and place it perpendicular over the other end so that they cross each other in an “X” shape. Sew along the diagonal line created by the intersection and then trim off any excess fabric.

6. What is an alternative method for joining bias strips if I want an invisible seam?
If you prefer an invisible seam, you can overlap one end of your bias strip over the other end and sew along the folded edges. This will create a smooth and seamless finish. Just make sure to trim any excess fabric to reduce bulk.

In conclusion, learning how to sew bias strips together can greatly enhance one’s sewing skills and broaden the possibilities of garment construction and design. By understanding the fundamentals of working with bias grain, such as its stretch and drape, one can create smooth and seamless connections between different fabric pieces.

Through careful preparation and precise stitching techniques, sewing bias strips together can create a fluid and continuous look in a garment, from curved edges to angled seams. This skill is not only useful in garment construction but can also be applied to various projects such as quilting, home decor, and accessories.

It is important to note that patience and practice are key in mastering this technique. It may take time to perfect the balance between tension, stitch length, and cutting precision when working with bias strips. However, the end result is well worth the effort.

Moreover, understanding how to sew bias strips together opens up opportunities for creativity. One can experiment with different fabrics, patterns, and techniques to achieve unique designs and textures. This knowledge also allows for more versatility in pattern options as many designs require bias strips for finishing.

Ultimately, mastering how to sew bias strips together not only serves practical purposes but also enhances one’s overall sewing skills and confidence. With proper execution, it can elevate a handmade garment from ordinary to
