Soft next-to-skin seams
The lofty texture helps reduce the hard, cord-like feel that ordinary thread can leave on seam allowances.

Madeira Aeroflock No. 100 · 1000m Miniking
Soft, fluffy coverage for overlocker and coverstitch loopers
Madeira Aeroflock is a lofty, textured polyester looper thread made to add softness, stretch and fuller coverage to overlocked and coverstitched finishes. It is especially useful where seams sit against the skin or where a decorative edge needs more body.
- Fluffy, voluminous texture covers the fabric edge with fewer visible gaps.
- High elasticity suits flexible seams on knit and stretch garments.
- Soft against the skin for lingerie, activewear, swimwear and babywear.

This is fluffy looper thread—not ordinary all-purpose sewing thread
Aeroflock is primarily chosen for the looper paths of an overlocker or coverstitch machine. For strong construction seams, it is commonly paired with a smooth thread such as Madeira Aerolock in the needle paths. Always follow your machine manual for permitted thread types and threading positions.
More coverage, stretch and comfort where it counts
Unlike a tightly twisted construction thread, Aeroflock has a soft, expanded structure. As the looper forms the stitch, the thread spreads across the fabric edge to create a fuller-looking, flexible finish.
Elastic performance
High stretch makes Aeroflock a practical choice for seams and hems that need to move with knit fabrics.
Full decorative coverage
Use the volume to make rolled hems, flatlock effects and exposed overlocking look richer and more deliberate.
Where Aeroflock works especially well
Lingerie and sleepwear
Create softer overlocked edges and flexible seams on garments that sit close to the body.
Sportswear and swimwear
Add stretch and comfortable coverage to active garments, performance knits and swim fabrics.
Babywear and children’s knits
Choose a soft looper finish for jerseys, bodysuits, leggings and other frequently worn stretch garments.
Rolled hems and flatlock effects
Let the bulky thread fill the stitch for decorative hems, visible flatlocking and colourful edge finishes.

Screen colour is a guide only. Displays, photography and lighting can change how thread appears. Match by the Madeira colour number and compare with a physical colour card or thread sample when an exact match matters.
Thread, test and balance before sewing the garment
Check the manual
Confirm which thread paths accept textured thread and follow the machine’s specified threading order.
Use the looper path
Place Aeroflock in one or both loopers according to the stitch and the side where you want the soft coverage.
Start gently
Because the thread is bulky, it may need less looper tension than smooth thread. Change settings in small steps.
Test a fabric offcut
Check stretch, coverage and stitch balance, then fine-tune tension, width, length and differential feed.
Tip: Pull textured thread through long, tight guides gently rather than forcing it. If your machine supports tying-on a new looper thread, follow the manual’s method and draw the knot through the path slowly.

Before you choose Aeroflock
What does “fluffy looper thread” mean?
It is a textured polyester thread with a soft, expanded structure. In a looper stitch it spreads out to give more coverage, stretch and softness than a tightly twisted construction thread.
Is Aeroflock ordinary overlocker sewing thread?
No. Aeroflock is the soft, bulky thread used mainly for coverage in looper paths. For the needle paths and strong construction seams, pair it with a smooth thread approved for your machine, such as Madeira Aerolock.
Can I put Aeroflock in an overlocker needle?
Treat Aeroflock primarily as a looper thread. Some machines or decorative techniques may permit textured thread elsewhere, but only use it in a needle path when your machine manual and the selected needle support it.
Can I use it in a coverstitch machine?
Yes, it is well suited to compatible coverstitch or coverlock looper paths for soft, stretchy hems and decorative coverage. Follow your machine’s threading diagram and test the stitch first.
Do I need more than one spool?
This listing supplies one 1000m spool. The quantity needed depends on the stitch: you may use Aeroflock in one looper, both loopers, or alongside other thread types. Check the machine manual and your planned thread layout.
Is it suitable for rolled hems?
Yes. Its volume helps fill rolled-hem stitches for a rich, even edge. Stitch width, length and tension still need to be tested on a fabric offcut.
Will it work on stretch fabric?
Aeroflock’s high elasticity is designed for flexible seams on knits and stretch garments, including lingerie, sportswear and swimwear. Correct differential feed and stitch balance are also important.
How should I choose a colour?
Use the four-digit Madeira colour number as the primary reference. Screen colour can vary, so use a physical Aerolock/Aeroflock colour card or thread sample when an exact match is essential.
Give stretch seams the comfortable coverage they deserve
Choose the Madeira colour number above, select the quantity required for your looper setup and test the stitch on your project fabric. Aeroflock’s fluffy texture is the finishing touch that makes overlocked and coverstitched seams feel as good as they look.
