Set up a four-thread overlocker in three essential colours
This Madeira Aerolock 125 kit gives you four matching 1200m Minikings each in Black, White and Pearl Grey. Choose a colour, place one spool on every thread stand of a four-thread overlocker and start with consistent thread across the complete stitch.
- 12 genuine Aerolock Minikings—four spools in each neutral shade.
- 14,400 metres total of strong, smooth No. 125 overlock thread.
- Ready for everyday projects across light, dark and mid-tone fabrics.
This listing is for the complete 12-spool box
You receive four Black, four White and four Pearl Grey Minikings. It is not one cone, not a choose-your-colour variant and not the separate 2500m Kingspool product.
Four matching spools in every colour
Each colour group supplies all four thread positions of a standard four-thread overlock stitch without mixing shades, thread constructions or spool sizes.

A practical neutral wardrobe for your overlocker
Black and White cover the fabric extremes, while Pearl Grey is a useful compromise when an exact colour match is unavailable. Because the seam is often inside the garment, these three shades handle a wide range of everyday sewing without requiring a full colour library.
- Use Black behind dark denim, navy, black and deep colours.
- Use White behind light cottons, linens and pale garments.
- Use Pearl Grey as a quiet mid-tone under prints and medium colours.
Strong seams with smooth, dependable feeding
Aerolock 125 combines bundled continuous polyester filaments with a fibrous outer layer. This core-spun construction gives the thread strength for hard-working seams while retaining the smooth handling needed for clean stitch formation.
Durable seam strength
Designed for seams exposed to regular wear, laundering and the movement of everyday garments.
Consistent stitch formation
Uniform No. 125 thread across every path supports balanced tension and tidy loops at overlocking speed.
Useful beyond one machine
Madeira approves Aerolock for sewing and overlock machines; it is also used on compatible coverlock setups.
Ready for three- and four-thread overlocking
Use three matching spools and keep the fourth as a ready replacement.
One complete four-spool colour group supplies both needles and both loopers.
You will need one additional matching spool if all five thread paths must use the same colour.
Useful at home, in a classroom or beside a new machine
New overlocker setup
Start with three dependable colours and enough matching spools to learn four-thread threading and tension.
Everyday garment construction
Finish knit and woven seams, trim raw edges and create durable seam allowances across common fabric tones.
Classes and workshops
Keep complete matching colour groups ready for demonstrations, student machines and practice samples.
Reliable neutral backup
Maintain a practical reserve for alterations, repairs and projects where the internal seam colour is not prominent.
Thread, test and balance before sewing the garment
Select the colour
Choose Black, White or Pearl Grey for the closest discreet match to the project fabric.
Fit every spool
Place one matching Miniking on each stand required by the stitch and use spool holders as directed.
Thread in sequence
Follow the machine manual’s threading path and order, ensuring every thread enters its tension system.
Test and fine-tune
Sew a folded offcut, then adjust tension, stitch length, width and differential feed for the fabric.
