When to Use Fluffy Sewing Thread in Your Overlocker Loopers

April 19, 2025

Looking for a softer, stretchier, more professional finish on your garments? If you sew with an overlocker, switching to a fluffy thread like Madeira Aeroflock in the looper threads can completely transform your results.

Whether you're sewing activewear, baby clothing, or lightweight knits, here's when and why you should use textured thread in your overlocker—and why Madeira Aeroflock is our top pick.

What Is Fluffy Thread (Also Known as Textured or Woolly Thread)?

Fluffy thread—also called woolly nylon, textured polyester, or stretch thread—is thicker and has a soft, slightly fuzzy texture. It expands when stitched, providing more coverage, elasticity, and comfort, especially on the inside seams of garments.

Madeira Aeroflock is one of the best fluffy threads available in New Zealand. Made in Germany, it’s specifically designed for use in overlocker loopers and is known for:

Exceptional stretch and recovery
Ultra-soft finish (great against the skin!)
Consistent, low-lint stitching
A wide range of rich, colourfast shades

Why Use Fluffy Thread in Your Overlocker?

If you’re wondering when to use Madeira Aeroflock or another fluffy thread, here are the top scenarios where it shines:

1. Stretch Fabrics and Activewear

If you're sewing:

Leggings
Swimwear
Lycra gym wear
Cotton/spandex blends
... then fluffy thread in your overlocker loopers is a must. It gives seams the stretch they need without popping or distorting, even during movement.

✅ Tip: Pair it with regular polyester thread in the needles and adjust your looper tension slightly lower.

2. Lingerie, Babywear & Seam-Against-Skin Projects

Madeira Aeroflock is incredibly soft, making it perfect for:

Baby rompers and onesies
Lingerie and undergarments
Pyjamas and lounge sets

The fluffy thread provides a cushioned seam finish that’s gentle against sensitive skin—ideal for babies and anyone with sensory needs.

🍼 Want soft seams for baby clothes? Use Aeroflock in both upper and lower loopers for maximum comfort.

3. Rolled Hems on Sheer or Lightweight Fabrics

Need a clean finish on delicate fabrics like:

Chiffon
Georgette
Voile
Organza?

Fluffy thread fills out rolled hems beautifully, giving a polished, professional edge—especially useful for eveningwear, bridal, or floaty tops.

4. Decorative Flatlock Seams

Using Aeroflock in a flatlock stitch creates a bold, decorative finish—great for sportswear or adding detail to knit garments. Try using contrasting colours for a high-end designer look.

🎨 We stock Aeroflock in a wide variety of colours so you can match or contrast with your fabric easily.

Tips for Using Madeira Aeroflock in Your Overlocker

🧵 Use it in the loopers only – Combine with standard polyester thread in your overlocker needles.

🔧 Lower your looper tension – Fluffy thread is thicker and needs less tension to feed smoothly.

🎯 Do a test run first – Always test on a fabric scrap to fine-tune tension and stitch quality.

🧺 Store it properly – Keep it clean, dry, and away from dust to prevent lint build-up in your machine.
