What do you do with the multiple drafts from your PhD thesis? Turn it into yarn and spin it! Creating something artful from this material was part of a process that helped sustain me during the 6 years it took to complete a PhD.
When I was writing my thesis and needed a break I would often go and create a piece of art. It was a shift from the mind to the body which I discovered fostered a reflective process as well as a creative one. The hands-on, physical aspect of creating a piece of art often gave me bit of space in my head to unpack my research ideas.
