What it is

A home studio that makes short runs of activewear, typically dozens to a few hundred pieces, for small brands that are too small for big factories. You cut and sew from their patterns or help refine them, using stretch fabrics.

Your first three steps

  1. Make a small sample set of leggings and tops and photograph them well
  2. Work out your cost per garment, including fabric, thread, labour and waste, and set a minimum order
  3. Contact small fitness brands and studios on social media and offer a paid sample run
Who pays

Independent fitness brands, gym and yoga studios, personal trainers and online sellers who want small minimum orders.

How it makes money

A price per garment, often with a fee for sampling or pattern work, and repeat orders when a brand's range sells well.
