The tear-resistant slit is a finish used to reinforce a discreet opening on a garment. It is mainly found at the bottom of a shirt cuff. It is made with a bias strip that prevents fraying and ensures a clean and durable finish. This detailed guide explains how to proceed step by step.
How to prepare the slit?
- Marking the slit location
Mark the future slit on the fabric by drawing a vertical line and cutting along it.
Set the height of the slit according to the garment model.
- Pressing the bias strip
You will press your strip to create a bias, then press it again folded in two.

How to sew the bias strip onto the slit?
- Positioning the bias strip correctly
Sandwich the sides of your slit inside the bias strip. When you reach the tip of the slit, position the bias 1 or 2mm from the edge to avoid creating small folds.

- Sewing the bias strip
Sew the bias strip in one go, 1mm from its edge.

How to form and finish the tear-resistant slit?
- Old tip of the slit
Fold the bias strip wrong sides together, aligning the edges precisely.
Flatten with an iron to mark the fold well and sew the small corner diagonally to secure the slit.

- Finishing the slit
Carefully press the slit to properly shape the bias strip.
Check that the slit is even and that the bias strip neatly covers the edges.

The tear-resistant slit is an essential technique to reinforce an opening on a garment while providing a clean and durable finish. By adding a bias strip and sewing precisely, you get a strong slit that resists wear and fabric tension. This method is ideal for shirt cuffs requiring a neat opening.
