Hey there, fellow sewing enthusiasts! As a bias tape supplier, I've seen my fair share of sewing projects, and I know how tricky it can be to sew bias tape on thick fabrics. But don't worry, I'm here to share some tips and tricks that'll make the process a whole lot easier.

First off, let's talk about what bias tape is. Bias tape is a strip of fabric that's cut on the bias, which means it's cut at a 45-degree angle to the grain of the fabric. This gives the tape more stretch and flexibility, making it perfect for binding curves and edges. You can find all kinds of bias tape, like Bias Binding Tape, Double Fold Bias Binding Tape, and Single Fold Bias Binding Tape.

Now, when it comes to thick fabrics, there are a few things you need to keep in mind. Thick fabrics can be heavy, stiff, and difficult to manipulate, so you'll need to choose the right bias tape and sewing techniques to get the best results.

Choosing the Right Bias Tape

The first step is to choose the right bias tape for your project. When working with thick fabrics, you'll want to use a wider bias tape to ensure that it can cover the raw edges of the fabric properly. Double fold bias tape is a great choice because it has a finished edge on both sides, which gives your project a professional look. You can find double fold bias tape in a variety of widths and colors, so you're sure to find one that matches your fabric.

Another thing to consider is the type of fabric the bias tape is made from. For thick fabrics, you'll want to choose a bias tape that's made from a sturdy fabric, like cotton or linen. These fabrics are strong and durable, and they'll hold up well against the wear and tear of your project.

Preparing the Fabric and Bias Tape

Before you start sewing, you'll need to prepare the fabric and bias tape. First, cut the bias tape to the desired length, adding a few extra inches to allow for overlap. Then, press the bias tape in half lengthwise, folding the raw edges towards the inside. This will create a finished edge on both sides of the bias tape.

Next, prepare the fabric by pressing it to remove any wrinkles or creases. If the fabric has a lot of bulk, you may want to trim the edges to reduce the thickness. You can also use a rotary cutter and a cutting mat to cut the fabric to the desired size and shape.

Sewing the Bias Tape

Now it's time to start sewing the bias tape to the fabric. There are a few different techniques you can use, depending on the type of bias tape and the style of your project.

Method 1: Machine Sewing

One of the easiest ways to sew bias tape on thick fabrics is to use a sewing machine. Start by pinning the bias tape to the edge of the fabric, with the folded edge facing towards the fabric. Make sure the bias tape is centered on the edge of the fabric, and that the raw edges of the bias tape are even with the raw edges of the fabric.

Next, sew the bias tape to the fabric using a straight stitch, about 1/8 inch from the edge of the bias tape. Make sure to sew slowly and carefully, especially when sewing around curves or corners. You may need to use a walking foot or a Teflon foot to help the fabric feed through the machine smoothly.

Once you've sewn the bias tape to the fabric, fold the bias tape over the raw edges of the fabric, and press it in place. Then, sew the bias tape to the back of the fabric using a straight stitch, about 1/8 inch from the edge of the bias tape. Make sure to sew slowly and carefully, and to backstitch at the beginning and end of each seam to secure the stitches.

Method 2: Hand Sewing

If you prefer to sew by hand, you can also sew the bias tape to the fabric using a running stitch or a slip stitch. Start by pinning the bias tape to the edge of the fabric, with the folded edge facing towards the fabric. Make sure the bias tape is centered on the edge of the fabric, and that the raw edges of the bias tape are even with the raw edges of the fabric.

Next, use a running stitch or a slip stitch to sew the bias tape to the fabric, about 1/8 inch from the edge of the bias tape. Make sure to sew slowly and carefully, especially when sewing around curves or corners. You may need to use a thimble to protect your finger from the needle.

Once you've sewn the bias tape to the fabric, fold the bias tape over the raw edges of the fabric, and press it in place. Then, use a slip stitch to sew the bias tape to the back of the fabric, about 1/8 inch from the edge of the bias tape. Make sure to sew slowly and carefully, and to hide the stitches as much as possible.

Finishing the Project

Once you've sewn the bias tape to the fabric, you'll need to finish the project by trimming the excess bias tape and pressing the seams. Use a pair of sharp scissors to trim the excess bias tape, leaving about 1/4 inch of overlap. Then, press the seams using a hot iron to flatten them and give your project a professional look.

If you're working on a project that has curves or corners, you may need to trim the bias tape to fit the shape of the fabric. You can use a pair of sharp scissors or a rotary cutter to trim the bias tape, making sure to cut it at a 45-degree angle to the grain of the fabric.

Tips and Tricks

Here are a few tips and tricks to help you sew bias tape on thick fabrics like a pro:

  • Use a sharp needle: When sewing thick fabrics, it's important to use a sharp needle to prevent the fabric from puckering or bunching up. A size 90/14 or 100/16 needle is a good choice for thick fabrics.
  • Use a walking foot: A walking foot is a special sewing machine foot that helps to feed the fabric through the machine evenly, especially when sewing multiple layers of thick fabric. This can help to prevent the fabric from shifting or bunching up, and it can make the sewing process much easier.
  • Use a Teflon foot: A Teflon foot is another special sewing machine foot that can be helpful when sewing thick fabrics. The Teflon coating on the foot reduces friction, which makes it easier for the fabric to slide through the machine.
  • Use a stabilizer: If the fabric is very thick or heavy, you may want to use a stabilizer to help support the fabric and prevent it from stretching or distorting. You can use a fusible interfacing or a stabilizer sheet to add stability to the fabric.
  • Take your time: Sewing bias tape on thick fabrics can be a slow and tedious process, so it's important to take your time and be patient. Make sure to sew slowly and carefully, especially when sewing around curves or corners, and to check your work frequently to ensure that the bias tape is straight and even.

Conclusion

Sewing bias tape on thick fabrics can be a challenge, but with the right tools, techniques, and a little patience, you can achieve professional-looking results. Remember to choose the right bias tape for your project, prepare the fabric and bias tape properly, and use the right sewing techniques to get the best results.
