What Kind of Interfacing Should I Use for a Jacket?

When it comes to creating a high-quality jacket, one of the most important considerations is the choice of interfacing. The right interfacing can make all the difference in achieving a professional and polished look. But with so many options available, it can be overwhelming to choose the best one for your specific project. That's where Madeira Aerolock Premium Serger thread comes in. This top-quality, core-spun thread is designed to withstand frequent washes and strain, making it ideal for use in jackets. Made from 100% core-spun polyester, it’s specifically designed for use in sergers/overlock and coverlock machines, such as the Janome CoverPro family of machines.

Do I Need Interfacing for Coat?

When it comes to making a coat, many sewers wonder if interfacing is necessary. The answer is that it depends on the type of coat youre making and the desired outcome. Interfacing is a material that’s used to add structure and stability to fabric, and can be particularly beneficial for coats to help them maintain their shape.

It can also help the lapels and collar to stand up properly. On the other hand, if youre working with a lightweight fabric or a coat with a more relaxed fit, interfacing may not be necessary.

In terms of which interfacing to use for a coat, there are a few options to consider. Fusible interfacing is a popular choice, as it can be easily ironed onto the fabric. This type of interfacing is available in different weights, so you can select one that matches the thickness of your coat fabric. Sew-in interfacing is another option, which is stitched onto the fabric by hand or machine. This type of interfacing generally provides a sturdier result but requires more time and effort to apply.

One thread that’s highly recommended for sewing coats and other heavy-duty projects is the Madeira Aerolock Premium Serger thread. This top-quality, core-spun thread is made of 100% core-spun polyester, ensuring durability and longevity. It’s designed to withstand frequent washes and strain, making it an ideal choice for coats that will be subjected to regular wear and tear.

If youre using a serger or overlock machine to construct your coat, the Madeira Aerolock Premium Serger thread is a perfect match. It’s compatible with machines like the Janome CoverPro family, known for their professional finish. This thread will provide the strength needed to hold the seams together, ensuring that your coat withstands the test of time.

When choosing interfacing, consider options like fusible or sew-in, and select a weight that matches your fabric.

How to Properly Apply Fusible Interfacing to Coat Fabric

  • Start by gathering your materials, including your coat fabric and fusible interfacing.
  • Pre-wash your fabric to prevent any shrinkage later on.
  • Cut your fusible interfacing according to the pattern pieces or desired shape.
  • Place the interfacing adhesive side down onto the wrong side of the fabric.
  • Press the interfacing with an iron on the appropriate setting, using steam if recommended.
  • Hold the iron in place for a few seconds, then lift and repeat over the entire area.
  • Allow the fabric to cool completely before moving or handling it.
  • Check that the interfacing has adhered properly by examining the fabric closely.
  • If any areas haven’t bonded well, reapply heat and pressure until they stick.
  • Trim any excess interfacing beyond the fabric edges to avoid bulkiness.
  • Continue applying interfacing to the remaining coat fabric pieces in the same manner.
  • Once all the pieces have been fused, follow your pattern instructions for sewing the coat.


By selecting the Madeira Aerolock Premium Serger thread, you can trust that your jacket's seams and edges will be professionally finished and ready to endure whatever adventures lie ahead.
