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 make 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 provides extra comfort by facilitating movement. This finish is ideal for garments requiring a small discreet opening on the sides.

How to prepare the fabric and mark the slit?

Draw the slit opening

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

Assemble the fabric pieces

• Stitch 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 point. Be careful not to go beyond it.
• Fold the edges of the slit inward, making a finishing 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 of length 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 ensure its strength 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 precisely, you will achieve a clean and durable finish, ideal for everyday clothing as well as more sophisticated pieces.
