How to apply bias binding on curves: our recommendations

Preparation of the bias tape

Before you begin, choose a tape that has enough flexibility. The polyester bias tape from Byetsa is ideal for beginners, as it offers a balance between manageability and durability, without wrinkles. Be sure to press the tape to avoid creases and have fine pins ready to secure it.

Open the tape and pin it

To know how to apply bias tape on curves, it’s key to unfold the tape, place it along the curved edge you want to finish, and pin it in place to keep it where you want. Start by pinning one end of the bias tape to the fabric edge, then continue pinning every few centimetres so it adapts to the curve. Don’t hesitate to make small notches along the edge of the tape if the curve is very tight; this will help avoid wrinkles and tension.

From Byetsa, we recommend using printed bias tapes, as they are perfect for adding a decorative touch to your projects.

Sewing machine adjustment

To avoid slipping when sewing curves, use a fine needle and adjust the machine’s tension according to the fabric type. Work at low speed and with smooth movements. Make frequent stops to adjust the direction of the tape. The key is to sew slowly and without forcing the fabric to avoid distorting the bias tape. Keep in mind that Byetsa’s elastic bias tape is an excellent option for sharp curves, as it adapts better to rounded shapes.

Choose the right width and type of bias tape

Choosing the right bias tape is crucial. For sharp curves or narrow edges, opt for thinner tapes like the Byetsa satin bias tape, which offers greater flexibility and better adaptability to tight contours without compromising aesthetics.

On the other hand, if you’re working on upholstery projects or garments with wider edges, the Byetsa cotton bias tape in wider widths can be ideal to provide the necessary reinforcement and durability, while maintaining its appeal.

Use precision tools

Fine pins and precision tweezers can be very helpful in this process. Place pins at short intervals to secure the tape without shifting. You can also use a bias tape foot on your sewing machine, which allows for more controlled tension adjustment and helps handle the tape on curves.

The Byetsa lamé bias tape is a decorative and festive option that fits precision projects, offering a striking metallic finish.

Make strategic cuts in the tape

If the curve is very tight, make small cuts or notches on the inner edge of the tape, especially where the curve is tightest. This will allow the chosen bias tape to fit more easily without creating pleats, maintaining a smooth appearance and achieving the desired finish.

Try basting first

To ensure the bias tape is in the exact position, you can baste the tape before sewing it by machine. This additional step is especially useful for complex projects or when working with delicate materials. Basting will allow you to visualise how the bias tape will fit the curve and make any necessary adjustments before the final stitching.

Continuous adjustment of the bias tape while sewing

While sewing the bias tape, especially on curves, it is essential to make adjustments frequently. The bias tape has some elasticity, but in tight curves, it’s important to handle it carefully, gently turning the fabric to avoid overstretching or forming wrinkles. Remember, when working with curves, patience and precision are key to achieving a clean and professional finish.

Iron between steps

To ensure the bias tape settles properly, use an iron on a low temperature with steam between each step. After each seam, press the tape on the curve with light pressure and steam, avoiding dragging the iron to prevent distorting the material. This step helps shape the tape and sets the seam for a polished final result.

Step 1: Initial Fixing and Alignment

Unfold the bias tape and place it along the left edge of the curve. If you want to learn how to apply bias tape on curves without wrinkles, it’s important to align the edges properly. Secure with pins at regular intervals. Instead of placing the fabric on a flat surface, slightly lift the fabric to work better with the curvature.

Step 2: Sew the First Fold

Use the sewing machine to follow the line of the tape, keeping the needle aligned with the fold of the tape. This first fold is key for securing and defining the contour, and helps keep the tape in place without shifting.

Step 3: Adjust and Close

Fold the tape over the edge and secure it with pins, covering the first line of stitching. Sew a few millimetres from the edge of the tape, ensuring it stays firm both at the top and bottom.

Step 4: Iron for the Final Finish

For a perfect finish, use a steam iron and apply light pressure without dragging it. This step is key when learning how to apply bias tape on curves correctly, as it helps settle the tape nicely on the curve, making it look polished, flawless, and professional.
