Silk embroidery threads are perfect for embroidery and craft projects. The luxurious threads of silk are soft and reflect light. Some silk embroidery threads are easy to work with, some others difficult. It is important to choose the right silk thread for the desired embroidery finish.

There are two types: filament silk thread and spun silk thread. Here we explain the differences between the two types of threads and how you can use them in different embroidery projects. 

What is Filament Silk Embroidery Thread?

Filament silk thread is made of fine strands, reeled right off the cocoon. Hence, it is also called reeled silk. It is glossy and can be easily differentiated from the spun silk thread as it is much stronger and difficult to pull apart. It is also more expensive than most threads. Pure filament silk thread has a high shine. 

The filament silk thread is of two types, twisted and flat. The twisted filament silk embroidery thread comes in a variety of twists and weights. Hence, you can use the twisted filament silk embroidery thread for stitching, handwork, and craft. The flat filament embroidery thread is more difficult to work with.

Many thread manufacturers make silk embroidery threads using filament silk. Examples are Gilt Sylke twist, silk Bella, silk Serica, and vineyard silk.

Silk was traditionally used in Japanese and Chinese embroidery. Gradually it made its entry in other markets as well. 

Some of the popular ways you can use the filament silk embroidery thread are:

  1. Handbags
  2. Heirloom projects
  3. Wedding gift items
  4. Bridal wedding gowns

As filament silk thread is stronger and shinier than spun silk, it can be used in projects curated as keepsakes. The silk thread strands can be separated and used to give different textures to your embroidery projects.

What is Spun Silk Embroidery Thread?

Spun silk, unlike filament silk thread, is made from broken cocoons and leftovers. It is spun into a thread similar to the filament one. Another major difference is that the spun silk is matte with a soft shine and is weaker than the filament silk thread. It has a compact and clean appearance with a good absorbing capacity. Though used for projects in place of cotton floss thread, it can become fuzzy.

Popular Ways to Use Spun Silk Thread

Spun silk thread is cheaper than filament silk thread. It can be widely used in various applications. 

Some of the embroidery applications for spun silk embroidery thread are:

  1. Best for beginners’ projects for it is easy to handle
  2. Projects where you need shorter strands of thread for embroidery
  3. Blended with other threads when working on embroidery

Care Tips for Silk Embroidery Thread

Silk embroidery threads have a natural sheen and can be used for various embroidery and craft projects. It should be treated with care. The thread can be hand washed in lukewarm water. Articles with silk thread embroidery can be washed with delicate soap and rolled in a dry cloth to remove excess water.

Most silk embroidery threads can be used for both machine stitching and hand stitching. Both filament silk threads and spun silk threads are suitable for embroidery projects. You can use them alone or combine them for a visual effect. Create beautiful patterns with the silk embroidery threads on your needlepoint projects.
