While her children were young, Drysdale decided to start a home-based garment manufacturing business. She called it "Snowy Peak" and employed outworkers to knit luxury clothes such as jumpers, hats, scarves and gloves for supply to a few Christchurch stores. She started with 10 outworkers, and by 1985, after four years operation, she had 500 working for her. Drysdale experimented with certified organic, eco-friendly wools and cottons. In 1996 she launched the world's first yarn that blended
possum fur with
merino wool, calling the new yarn "merinomink". She also began to export her clothes to Australia, Europe, Japan and Canada, expanded operations in Christchurch with a cafe and retail store, and opened stores in
Auckland and
Queenstown. In 1999 the brand received international attention when it was chosen to provide garments for world leaders attending the
Asia-Pacific Economic Cooperation Forum in Auckland. President
Bill Clinton particularly admired his sweater, and he and his family became fans and customers. In 2014, Drysdale began using a second new textile which she calls "kapua" - a mixture of cashmere, silk and possum - which had been in development since 2000. ==Charity foundation==
