Complete Guide: How to Make a Tear-Proof Slit?

The indecipherable 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.

Set the height of the slit according to the garment model.

• Prepare the bias strip

Fold the bias strip right sides together lengthwise.

Iron it to mark the fold well.

• Position the bias strip

Pin one side of the bias strip to one side of the slit , edge to edge with the fabric.

Check that the bias tape is correctly positioned and aligned before sewing.

How to sew the bias tape onto the slit?

• Assemble the first side of the slot

Stitch the bias strip 2.5 mm from the edge , following the slit line.

Sew a precise and even seam, holding the fabrics together well.

Once you have finished sewing, raise the presser foot and adjust the fabric if necessary.

• Fix the second side of the slot

Fold the bias strip over to the other side of the slit.

Make a second seam identical to the first to secure the bias along the entire length of the slit.

How to form and finalize the indecipherable cleft?

• Old slot tip

Fold the bias tape inside out, aligning the edges well.

Flatten with the iron to clearly mark the fold.

• Topstitch to stabilize the slit

Topstitch 2mm from the edge of the bias tape to ensure a durable attachment.

Use an elongated straight stitch and backstitch at the beginning and end of the seam.

• 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.

The indecipherable slit is an essential technique for reinforcing an opening on a garment while providing a neat and durable finish. By adding bias tape and precise stitching, you achieve a strong slit that resists wear and tear and fabric stress. This method is ideal for shirt cuffs that require a neat opening.
