Ysolda says in the intro, “Through many conversations about choosing a size, substituting yarns, taking measurements and adapting shaping, the key thing that emerged was that most knitters would like to feel more in control when making garments, like they had a better ability to visualise what they wanted to create and actually end up with what they planned. Before getting to the patterns, the book goes through some things that I hope will help you get the results you want from both these patterns and any other garments that you want to knit.”
