How to Sew Silk: Expert Tips and Techniques

When we think of silk, its graceful drape in the breeze, and smooth feel against the skin often come to mind. However, these delightful qualities can pose challenges when learning how to sew silk on a sewing machine. Its slippery nature can make it difficult to handle, making every step challenging. But fear not! In this article, we’ll tackle these challenges head-on, providing solutions to ensure a smooth sewing experience with silk.

Understanding Silk Fabric

Silk isn’t just one type of fabric; rather, it’s a versatile fiber that can be processed in various ways to achieve different textures and effects. To make informed choices when sewing, it’s crucial to grasp the distinctions between the different types of silk and their unique characteristics. By doing so, you can select the perfect silk fabric for your project, ensuring both quality and satisfaction.

How to Prepare for Sewing Silk?

  • Preparing Materials 

#Pins and Needles

Opt for silk pins or ultra-fine pins for fixing. The size of the needles should be matched to the weight of the fabric. Typically, we use needles in sizes 60/8, 70/10. These pins and needles are designed to be sharper and more delicate, avoiding leaving behind unwanted holes in the fabric.

#Threads

Generally, 100% cotton threads are chosen as they are less likely to cause damage to silk and offer strength. Besides, high-quality polyester threads are also a viable option. While silk thread blends seamlessly with the fabric, it can’t handle sewing entire garments due to its slippery nature. 

  • Preparing Sewing Machine

Begin by cleaning the machine thoroughly to remove lingering machine lubricant or dust, which can leave stains on your silk. Next, perform a trial run using scrap fabric to check for proper machine operation. Pay attention to needle size, stitch length, and tension settings, especially if you’re new to sewing. 

  • Pre-washing Silk Fabric

It’s wise to pre-wash silk fabrics before starting silk sewing, though they are pre-shrunk during manufacturing. Pre-washing helps prevent further shrinkage. If you skip pre-shrinking, dry-cleaning is the only option after making the garment. Additionally, pre-washing silk helps avoid water stains in subsequent steps.

How to Sew Silk?

  • Marking

When marking patterns on silk fabric, consider sewing tailor’s tacks. Tailor’s tacks offer an effective way to transfer pattern details onto your fabric. Avoid using chalks or pens directly on silk, as they can potentially bruise your delicate material.

  • Cutting

Cutting silk can be tricky, especially for beginners. One method is to create a “sandwich” with tailor tacks or silk pins to secure the silk between two sheets of paper. You can also apply starch spray stabilizer to the silk, giving it a paper-like texture that makes cutting easier. Using weights to hold the silk in place is also effective.

When it comes to tools, a rotary cutter is a great choice. It allows for cutting on a flat surface, which keeps silk from slipping during cutting. If you don’t have a rotary cutter, using sharp shears with new blades is a good alternative to ensure clean cuts.

  • Stitching

For beginners, it’s essential to test the stitch length before you stitch silk fabrics. Generally, we select 1.5-2 mm stitch lengths for silk fabric in lightweight and 2-2.5 mm stitch lengths for heavier silk fabrics.

When stitching, your silk fabric is likely to be caught or sucked into the throat plate, you can cover the hole of the throat plate with transparent tape. Another useful tip is to place a tissue paper under your silk fabric while stitching, then tear it away when you’re finished.

During stitching, gently pull the silk fabric from both ends with appropriate tension to ensure a smooth surface and keep the fabric from puckering. If puckers persist, try a smaller or new needle. Stitching slowly and carefully guides the fabric to stay aligned with your design.

  • Pressing

When pressing silk, there are a few important tips to keep in mind. 

  1. Use the lowest temperature setting or the silk mode on your iron. 
  2. Place an organza press cloth between the iron and the silk to avoid direct contact. 
  3. Use an up-and-down motion to prevent friction damage, instead of moving the iron side to side.
  • Seam Finishes

Securing raw cut edges is essential to stop silk fabrics from fraying. We will introduce three common ways to deal with those annoying cut edges.

#Pinking Shear

This method is ideal for beginners. Pinking shears are specialized scissors with serrated blades that produce a zigzag edge on fabric. Simply cut the raw edges with these shears for a tidy finish. This helps to control fraying but doesn’t completely prevent it over time.

#Sewing French Seam/ HongKong Seam

Sewing French seam is suitable for delicate and sheer fabrics like silk. It offers a clean and neat appearance both inside and outside of your garment. On the other hand, the Hong Kong seam is better for medium-weight silk or heavyweight silk by binding the edges with bias tapes.

#Overlocking with a Serger

Overlocking silk fabric with a serger in a 3-thread setup is both easy and effective for creating sturdy seams. This method is best for those who already have a serger or are passionate about sewing because investing in a serger can be costly and take up space. 

  • Hem Finishes

For lightweight silk, opt for a baby hem or rolled hem. These narrow, nearly invisible hems maintain the natural drape of silk fabrics.

For medium-weight silk, a bias tape hem is ideal as it secures the edge and adds a unique touch, especially if the tape is a contrasting color. 

For heavyweight silk, a hand-sewn hem with hem tape is recommended. The hem tape supports the fabric’s weight, ensuring a neat and durable finish.                        

  • Adding Embellishments

Opt for fine, sharp needles and silk thread when adding embellishments to silk. Lightweight embellishments like sequins, beads, or lace are ideal to prevent the fabric from being weighed down. These choices help create a clean and delicate finish.

Conclusion

In conclusion, learning how to sew silk can elevate your craftsmanship and accomplish your unique design. Use silk pins, fine needles, and suitable thread. Pre-wash fabric, mark patterns carefully, and choose the right seam and hem finishes. Adding embellishments enhances appeal.
