  • Repairs in high-wear areas
  • Visible decorative seams when a bold effect is desired

Sewing tips

Use a suitable needle - denim or leather needles work better with thicker thread. Adjust the sewing machine tension and stitch length: with extra strong threads, slightly longer stitches are often useful so that the material is not bunched up too much. Always test on a scrap of fabric first to check the needle, thread tension and stitch pattern. For hand sewing, a blunt saddler's needle helps to guide the thread through several layers.

What makes Extra Strong threads special?

Extra Strong threads offer increased tear resistance and good wear protection compared to standard sewing threads. They are manufactured in such a way that they remain stable even under stress and sewing seams do not tear out so quickly. This makes them the ideal choice for projects where safety and durability are more important than invisible sewing.

Consider when buying

  • Color choice: Choose contrasting colors for decorative seams or tone-on-tone for subtle joins.
  • Needle and machine settings: Make sure they are compatible with your sewing machine.
  • Quantity: Plan a little more thread if you are sewing thick sewing with several layers.

If you are unsure which thickness is right for you, we will be happy to advise you in person - online or in the store in Vienna. Die Stoffschwester will help you find the right Extra Strong thread for your next project.
