Method 1: Iron-On Patch (Fastest — 5 Minutes)

  1. 1

    Choose a matching or contrasting denim patch

    Iron-on denim patches are available at haberdashery stores, Spotlight, and online. Buy in a colour that matches your jeans for an invisible repair or a contrasting colour for a visible statement.

  2. 2

    Cut patch 2cm larger than the hole on all sides

    The patch needs to extend well beyond the hole to adhere to sound fabric. Round the corners — rounded patches are less likely to peel at the edges than square ones.

  3. 3

    Apply to the inside of the jeans with a hot iron

    Turn the jeans inside out. Place the patch adhesive-side down over the hole. Cover with a damp cloth. Press firmly with a hot iron (cotton setting) for 45 seconds. Let cool before moving. Turn right-side out and check the hole is completely covered.

  4. 4

    Sew around the edges for durability (optional)

    Iron-on patches can peel over time with washing. For a more permanent repair, sew around the perimeter of the patch with matching thread in a straight or zigzag stitch. This is especially important for high-stress areas like knees and inner thighs.

Method 2: Visible Mending (Sashiko Style)

Sashiko is a Japanese embroidery tradition now popular in Western visible mending. Place a patch on the outside or inside. Using a contrasting thread colour and simple running stitches in geometric patterns (crosses, waves, diamonds), stitch through both layers over and around the damaged area. The result is intentionally decorative and unique — the repair becomes a feature, not something to hide.

Method 3: Sewing Machine Darning

For a seamless-looking repair: place a patch inside. Set sewing machine to a dense zigzag stitch. Sew back and forth over the hole and surrounding weak fabric in parallel rows, building up a woven fabric texture. This is effectively machine darning and produces the most durable and natural-looking repair for worn-through denim.

Extend jeans life from the insideWhen jeans are new, iron-on a patch inside the knees and inner thighs before they wear through. This preventive reinforcement adds months or years to the life of jeans in high-wear areas.

Frequently Asked Questions

Yes — iron-on patches that are also sewn around the edges are fully washable. Iron-only patches can withstand machine washing but may eventually peel at corners with repeated washing. Washing inside out and in a cold cycle reduces stress on patches. High-temperature tumble drying weakens the adhesive fastest — air dry for longest patch life.
Inner thigh is the highest-stress area of jeans and the hardest to patch durably. The machine darning method is best — it rebuilds the fabric structure rather than just covering it. Use a patch on the inside and darn over both layers. Iron-on patches alone pull away quickly in this location. For severe inner thigh wear, cutting and re-hemming the jeans as shorts is sometimes the most practical option.
