Amy Twigger Holroyd is a knitwear designer-maker whose work researches the potential of re-knitting: reworking existing items using knit-based techniques, skills and knowledge. Reworking existing items would have been an integral element of everyday life in the past, but such practices have fallen out of favour. This, Twigger Holroyd points out, restricts the advantages of knitting in terms of sustainability, as it mirrors – rather than challenges – the linear production-consumption model of the mainstream fashion industry. Her chart The spectrum of re-knitting treatments visualises different instructions for repurposing garments, providing seemingly endless variations which we can see employed on her tinkered Re-knitting ‘tester’ jumper. Accompanying the jumper are a series of step-by-step photographs, showing us how we can ‘cardiganise’ or add afterthought pockets, frills or cuffs to any knitted garment.
