Sustainability has become a key priority within textiles and the associated industries. Whilst there has been a move towards more sustainable practice, there is still some way to go. A multifaceted holistic approach is needed to facilitate meaningful and effective change. Craft practice, including handweaving, has long been regarded as being a more sustainable alternative to mass production as it promotes the production of high-quality goods and encourages slow rates of consumption. Additionally, handweaving has the potential to contribute via a range of other strategies including, but not limited to, modular design, on-demand localised production, added value through customisation and more. The Chapter firstly presents a review of the role of craft, craft-based design and handweaving in relation to key models of sustainability and the circular economy is a particular area of focus. It then draws upon a case study of practice, undertaken by the first author, which focussed on the incorporation of the design of end products into the handweaving process. Prior professional design experience in footwear and woven textiles enabled the production of a series of fully-fashioned, low waste handwoven sandal upper designs. Practice was used to support data collection and qualitative data analysis revealed insights into the opportunities and limitations of the design methods and approach. Key areas of potential for handweaving to contribute to the advancement of sustainable design practice are identified. They are then mapped against key principles of the circular economy and a number of strategies such are identified which can contribute to the advancement of sustainable design practice. The Chapter focuses on the potentiality of the approach and future testing is required to further validate the theories presented.
