Madeira Aerofil No.120 Sew All 400m 100% Polyester thread

Madeira Aerofil 120 is a polyester sew-all thread sold here as 100m spools in a wide range of colours, each identified by its own colour number. It's a fine to medium weight thread (dtex 135 x 2, denier 120 x 2) suited to general sewing on lighter and mid-weight fabrics.

Pick your spools by colour number to match your fabric or existing project. Because it's a sew-all thread, the same Aerofil 120 works across dressmaking, children's clothing, sports and workwear, so the main decision is simply which colour you need rather than which weight.

If you're restocking a thread box, it's worth checking the colour numbers against what you already own, as Madeira's numbering is consistent across the Aerofil range.
