A rip-stop slit is a finishing touch used to reinforce a discreet opening on a garment. It is most commonly found at the bottom of a sleeve or cuff. It is made with a bias tape that prevents fraying and ensures a clean, durable finish. This detailed guide will show you how to do it step by step.
How to prepare the slot?
- Trace the location of the slot
Mark the future slit on the fabric by drawing a vertical line and cutting on it.
Set the height of the slit according to the garment model.
- Iron the bias tape
You will iron your strip to create a bias then iron it again in two.

How to sew the bias tape onto the slit?
- Position the bias correctly
Sandwich the sides of your slit in the bias tape. When you reach the tip of the slit, position the bias tape 1 or 2 mm from the edge so as not to create small folds.

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

How to form and finalize the tear-proof slot?
- Old slot tip
Fold the bias tape inside out, aligning the edges well.
Flatten with the iron to mark the fold and sew diagonally the small corner to secure the slit.

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