How To Embroider On Knitting: A Professional Guide To Surface Embellishment

Embroidering on knitting requires balancing tension to prevent fabric distortion while ensuring the thread remains secure within the shifting, elastic structure of the knit stitches. By utilizing surface duplicate stitch, Swiss darning, or freehand embroidery techniques, you can transform plain knitted garments into bespoke pieces using non-stretching fibers and stabilized backing methods.

Essential Preparation and Material Selection

Successfully adding embroidery to a finished knit piece relies on matching the weight of the embroidery thread to the weight of the knitted yarn. The primary challenge is that knitting is a dynamic, elastic structure, while most embroidery is static. If the tension is too high, the embroidery will cause the knit fabric to pucker; if it is too low, the work will look sloppy or unravel.

• Essential Tools:
  
  
  • Tapestry needles: Size 22 or 24 for medium weight (worsted), Size 26 for finer gauges.
  • Embroidery hoops: Essential for maintaining consistent tension, but use a spring-tension or wooden hoop wrapped with cotton tape to prevent damaging the yarn.
  • Embroidery Floss: Cotton six-strand floss, crewel wool, or matching fingering-weight yarn for heavy-duty motifs.
  • Wash-away stabilizer: Mandatory for complex designs to prevent the knit stitches from pulling out of alignment.
• Prerequisite Standards:
  
  
  • The knit fabric must be blocked and fully dried before embroidery begins.
  • Work on a flat, supported surface; do not embroider while wearing the garment.
  • Estimated duration: 2 to 6 hours depending on motif density and gauge.

Technical Execution of Embroidery Techniques

Step 1: Stabilizing the Knitted Canvas

Before marking your pattern, identify if the knit structure is stable enough to support your design. For light or loose-gauge knits, apply a water-soluble stabilizer to the back of the work. This provides a temporary grid and prevents the needle from snagging or pulling the yarn loops. If using a pattern, use a water-soluble fabric marker to transfer your design onto the stabilizer or directly onto the knit fabric, ensuring you do not stretch the stitches while marking.

Step 2: Selecting and Preparing the Thread

For traditional embroidery stitches like the backstitch or chain stitch, utilize stranded embroidery floss. For most worsted-weight knitting, use three strands of floss. If you are performing duplicate stitch—which mimics the appearance of the underlying knit—use a yarn identical in weight and fiber content to the garment itself. Always cut your thread to lengths no longer than 18 inches to prevent tangling and excessive friction damage to the base yarn.

Step 3: Executing the Duplicate Stitch (Swiss Darning)

This is the most common technique because it mirrors the V-shape of a stockinette stitch. Insert your needle from the back of the work to the front, coming up through the base of a V. Pass the needle under the two legs of the stitch above, then back down into the same hole where you originally exited. This essentially "knits" a new stitch on top of the old one.

Pro-Tip: Keep your tension loose. If you pull the needle too tightly, you will compress the underlying stitch and create a dimple in your fabric.

Step 4: Applying Surface Embroidery Stitches

For freehand designs (flowers, stems, letters), use a stem stitch or a backstitch. These stitches are structurally sound and handle the stretch of knit fabric better than satin stitches. Secure your thread by weaving the tail into the back of the stitches rather than tying knots, as knots will create bumps that can be felt against the skin.

Warning: Never use long, floating threads on the back of the embroidery, as these will snag on jewelry or fingers when putting the garment on.

Material Compatibility and Tension Thresholds

Troubleshooting Common Embroidery Failures

• Fabric Puckering and Distortion
  
  
  • Root Cause: The embroidery thread is too thick or the tension is too high, preventing the knit fabric from resting naturally.
  • Actionable Fix: Remove the thread and re-do the motif using a thinner strand of floss or a looser stitch. Always use a hoop to ensure the fabric remains flat during the process.
• Embroidery Thread Snagging
  
  
  • Root Cause: The needle is too sharp, or the knit yarn has a high mohair content, causing fiber friction.
  • Actionable Fix: Switch to a blunt-tipped tapestry needle. If working with fuzzy yarn, use a light coat of water-soluble stabilizer to lock the fuzz in place while you work.
• Design "Sinking" into the Knit
  
  
  • Root Cause: Inadequate structure or low-contrast yarn selection.
  • Actionable Fix: Work over a piece of water-soluble stabilizer to keep the design on the surface of the fabric. Once finished, rinse the stabilizer away, and the design will sit prominently atop the knit stitches.

Frequently Asked Questions

Do I need to knot the embroidery thread when starting?

No, knots should be avoided because they create uncomfortable lumps and may eventually pull through the space between knit stitches. Instead, secure your thread by weaving the tail into the purl bumps on the back of the work for several inches before beginning your design.

Can I embroider on a finished sweater that has already been worn?

Yes, but you must ensure the garment is freshly laundered and blocked. If the sweater has significant pilling, remove the pills with a sweater shaver first to ensure a smooth, professional surface for your needlework.

Is there a specific type of needle required for knitting?

Yes, use a tapestry needle with a blunt tip. A sharp embroidery needle will pierce the fibers of your knitted yarn rather than sliding between them, which can lead to thinning and eventual holes in the garment.

How do I keep the embroidery from stretching out of shape?

The secret is to match the elasticity of your embroidery to the garment. Use a stabilizer to lock the fabric in place while working, and choose stitches that allow for minor movement, such as the backstitch, rather than rigid, non-stretchy stitches like long satin stitches.

What is the best way to clean an embroidered knit item?

Always hand-wash the item in cold water with a gentle wool wash. Never wring or twist the garment, as this can cause the embroidery to pucker or distort. Lay the item flat on a clean towel and reshape it to its original dimensions before drying.
