How to repair silk fabric

Updated February 21, 2017

Silk fabric differs in thickness and weave. Silk is a natural fibre harvested from the cocoons of silk worms. Because of its delicate nature, silk degrades when exposed to chemicals and acidity; and shreds and deteriorates over time and with exposure to light. Holes or tears in silk may be repaired with fusible fabrics or patched with silk, but repairs are rarely invisible. Discoloured or yellowed silks can be treated with vinegar.

Patching silk with fusible fabric

  1. Measure the rip or hole with a ruler and cut a piece of one-sided fusible fabric 1.3 cm (1/2 inch) longer and wider than the rip/hole. Fusible fabrics are sold at craft and fabric shops. Purchase the thinnest fusible fabric possible. Most silk is thin and fusible fabric will be detectable under the silk.

  2. Use embroidery or finger nail scissors to snip away any jagged edges to the rip/hole. Turn the item inside out.

  3. Arrange the silk on the ironing board so the wrong side of the garment or fabric is facing you. Pull the edges of the rip/hole as close together as possible without bunching or puckering the fabric.

  4. Set the iron on a silk setting. Place a pressing cloth or thin dishtowel over the rip/hole and press the edges of the rip/hole flat. Remove the cloth.

  5. Centre the fusible fabric patch over the hole/rip with the fusible, adhesive side touching the fabric. Spray the pressing cloth with water. Place the damp cloth on top of the fusible fabric patch. Press the iron onto the cloth, onto the fusible patch, over the hole/rip in the silk. The pressing cloth eliminates scorching of the delicate silk. Hold the iron over the cloth and patch for the fusible fabric manufacturer's recommended amount of time.

  6. Remove the cloth. Turn the garment or fabric right side out.

Patching silk with a sewn silk patch

  1. Measure the rip or hole. Use similar silk fabric or fabric cut from an inside seam or hem of the same garment to cut a triangular patch 1.3 cm (1/2 inch) longer and wider than the rip/hole. A three-sided patch is neat and covers rips and holes well. A patch from like or the same silk is also good for covering spots of rotten or brittle fabric.

  2. Trim the jagged edges of the rip or hole with embroidery scissors. Lay the silk on a flat surface with the right side of the silk facing you. Thread a needle with one-ply silk thread in as close a colour match as you can manage. Tie a knot at the end of the thread.

  3. Place the triangle patch over the rip/hole with the triangle bottom running in the same direction as the fabric's grain. Fold one patch edge under. Pin. Fold the other two edges under and pin. Sew the three patch sides onto the silk using a very tiny running stitch and sewing as close to the patch edges as possible.

  4. Move the needle in toward the patch centre 2.5 cm (1 inch) and sew a second row of stitches, in the shape of the triangle along the edges using a running stitch. Turn the silk inside out. Lay the patched rip/hole onto a flat surface.

  5. Sew the jagged edges of the hole/rip on the inside of the patch using an oversewing stitch or whipstitch. Be careful not to snag the patch fabric beneath.

  6. Cover the patch with a pressing cloth. Press with an iron set on a silk setting.

Treating discoloured silk

  1. Place the silk in a container. Fill the container with cold water. Add the manufacturer's recommended amount of washing powder for delicates. Wash the silk gently using a kneading motion. Loosely squeeze the silk in the water. Rinse the fabric in a sink in cool water until all detergent residue is removed.

  2. Refill the container with cold water. Add &118 ml (1/2 cup) vinegar. Immerse the silk in the vinegar solution. Rinse the silk in the sink with cold water. Never bleach silk. Bleach destroys silk fibres.

  3. Lay a towel onto a flat surface. Place the silk as flat as possible on top of the towel. Roll the silk in the towel, gently pressing the moisture from the silk fabric. Never twist silk. Hang the silk to dry over a shower curtain rod.

  4. Tip

    To tell if fabric is silk, burn a tiny snip from a hem or inside seam. Silk burns leave behind a powdered ash and will emit a foul odour. There are bonding powders on the market that fill pin holes in silk caused by insects and age. These powders are available online and at fabric shops. Avoid ironing silk whenever possible. If you must iron silk, always use a pressing cloth.
