How to fix ripped pants in the crotch with invisible darning

You will learn to close a crotch blowout so the repair blends into the fabric and holds up to wear. It suits anyone with basic machine or hand sewing skills. You need matching thread, a denim needle and an iron, and you should practice on scrap fabric first.

Steps

  1. Turn the pants inside out and trim any loose, frayed threads around the tear with small scissors. Keep the edges as even as you can so the patch sits flat.

  2. Mark the full extent of the tear with tailor's chalk or a fabric pen, going a little past each end. Damage often spreads further than the visible hole.

  3. Press the area flat with an iron on a setting that suits the fabric. A flat surface makes the stitching lines easier to keep straight.

  4. Cut a patch from similar fabric or a hidden part of the garment, such as a hem. Make it larger than the tear so it supports the weak edges.

  5. Pin or baste the patch behind the tear on the inside. Line up the fabric grain so the patch does not pull the pants out of shape.

  6. Set the machine to a narrow zigzag or darning stitch and fit a denim needle. Test the stitch length and tension on scrap fabric first.

  7. Stitch back and forth across the tear in close parallel lines, catching both the patch and the torn edges. Overlap the lines slightly until the gap is filled.

  8. Turn the pants right side out and check the repair. Add more stitching over thin spots, then press the area flat with the iron.

  9. Trim the excess patch on the inside, leaving a small border around the stitching. Wash the pants inside out to protect the repair.

Tips and common mistakes

Practice the zigzag and darning stitch on scrap fabric before you touch the pants.

Match the thread color closely to the fabric so the repair stays invisible.

Go slowly around the curved crotch seams so you do not stitch through both legs.

Keep fingers clear of the needle and unplug the machine before changing needles.

Questions

Can I do this repair by hand without a sewing machine?

Yes. Use a hand darning needle and a simple running or back stitch in close rows over the patch. It takes longer but holds well on small tears.

Will the repair be visible from the outside?

With matching thread and a dense zigzag over a fabric patch, the repair blends in well. It shows more on thin or light-colored fabric.

What if the fabric around the tear is very thin?

Use a larger patch to cover the weak area, not just the hole. Thin fabric will tear again next to the repair if you only stitch the gap.
