Machine Embroidery on Sweaters and Knitted Fabrics: What You Need to Know
Understanding the Nature of Knit Fabrics
Knits are stretchy, soft, and textured. While this makes them incredibly comfortable to wear, it also poses challenges for embroidery:
They stretch easily, especially side-to-side.
They can snag or distort if hooped too tightly.
Stitches may sink into the fabric without proper support.
That’s why preparation is key.
Choosing the Right Embroidery Design
When working with knits and sweaters, design choice matters more than ever.
Best Design Types:
Low-density designs (less filled areas)
Sketch-style or outline designs
Watercolor or hand-drawn effects
Avoid:
Dense, heavy fill designs that may pucker or distort
Small text or overly detailed logos (especially on looser knits)
Stabilization Is Everything
Stabilizers are your best friends when embroidering on stretchy materials. For knits, you’ll usually need a combination of top and bottom stabilizers.
Recommended Setup:
Bottom stabilizer: Medium-weight cut-away or tear-away (cut-away is better for stretch)
Top stabilizer: Water-soluble film (WSS) or heat-away film to prevent stitches from sinking into the loops
Hooping & Fabric Preparation
Knits should never be hooped tightly like woven fabric. That could stretch them out and cause distortion once removed.
Use temporary adhesive spray to attach fabric to stabilizer before hooping
Consider floating the fabric (hoop just the stabilizer and stick the fabric on top)
Use magnetic hoops when possible — they’re gentle on knits
Don’t:
Overstretch the fabric in the hoop
Embroider without a top stabilizer on sweater textures
Needles and Thread
Using the right needle prevents damage to the fabric’s loops.
Needle: Ballpoint (jersey) needles – they glide through without piercing the loops
Thread: Polyester or rayon embroidery threads – strong yet soft enough for knits
Finishing Touches
After the embroidery is done:
Remove the top stabilizer with warm water or heat (depending on type)
Carefully trim the excess cut-away stabilizer from the back
Steam or press lightly with a cloth on top (don’t iron directly!)
