The tear-proof slit is a finish used to reinforce a discreet opening on a garment. It is mainly found at the bottom of a sleeve cuff. It is made with a bias tape 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?
- Mark the location of the slit
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 pattern.
- Iron the bias tape

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

- Sew the bias tape
In one go, sew the bias tape 1mm from its edge.

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

- Finish the slit
Carefully iron the slit to properly shape the bias.
Check that the slit is even and that the bias neatly covers the edges.
