How to make a slit in a hem?

The slit in a hem is an elegant and functional finish, allowing better ease of movement and a neat aesthetic result. It is often found on the sides of a top, at the bottom of pants, or even on some skirts. This guide explains step by step how to create a clean and well-structured slit.

What is a slit in a hem and why use it?

The slit is an opening located along a seam. It not only adds an aesthetic touch but also extra comfort by allowing easier movement. This finish is ideal for garments that require a small, discreet side opening.

How to prepare the fabric and mark the slit?

Mark the slit opening

• Set the height of the slit on the fabric. Generally, it is between 6 and 15 cm depending on the pattern.
• Draw a vertical line where the slit will be made, marking a backstitch point at the base.

Assemble the fabric pieces

• Sew the seam 1 cm from the edge up to the previously defined backstitch.
• Make a backstitch to reinforce the seam and prevent it from coming undone.

How to open and prepare the edges of the slit?

Open and prepare the slit

• Open the seam at the slit by carefully cutting up to the stop stitch. Be careful not to go beyond it.
• Fold the edges of the slit inward, creating a finished hem to prevent fraying.

Secure and sew the sides of the slit

• Sew the sides of the slit individually with a reinforcement stitch, using a straight stitch with a length of 2.5 mm.

How to finish the slit and ensure a clean finish?

Turn and press the slit

• Turn each side of the slit right side out and press the seam allowances flat with an iron to ensure a neat finish.

Secure the base of the slit

• Make a stay stitch at the base of the slit to secure it and prevent it from opening further over time.

Final pressing

• Do a final pressing to properly shape the slit and ensure a flawless hold.

Conclusion

The slit in a hem is a simple yet effective technique that adds elegance and functionality to your garments. By following these steps carefully, you will achieve a clean and durable finish, perfect for everyday wear as well as more sophisticated pieces.
