How to Make a Slit in a Hem?

A slit in a hem is a stylish and functional finish, allowing for greater ease of movement and a neat aesthetic. It's commonly found on the sides of a top, at the bottom of pants, or even on some skirts. This guide will take you step-by-step through how to create a clean, well-structured slit.

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

A slit is an opening located in the extension of a seam. It not only adds an aesthetic touch but also provides additional 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?

Trace the opening of the slit

• Determine 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 stopping point at the base.

Assemble the fabric pieces

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

How to open and prepare the edges of the slot?

Open and prepare the slot

• Open the seam at the slit by carefully cutting up to the stopping point. Be careful not to go past this point.
• Fold the edges of the slit inwards, making a finishing hem to prevent fraying.

Fix and assemble the sides of the slot

• Sew the sides of the slit together individually with a reinforcing seam , using a 2.5 mm straight stitch .

How to finalize the slot and ensure a clean finish?

Turn over and iron the slit

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

Fix the base of the slot

• Place a support stitch at the base of the slit to ensure its strength and prevent it from opening further over time.

Final ironing

• Do a final ironing to shape the slit and ensure it fits perfectly.

Conclusion

Slitting a hem is a simple yet effective technique that adds elegance and functionality to your garments. By following these steps precisely, you'll achieve a clean and durable finish, ideal for everyday wear as well as more sophisticated pieces.
