Stop letting numbers intimidate you. In Math for Knitters, Kate Atherley, author of Custom-Fit Hats, breaks down the essential calculations every knitter needs to understand in order to knit with confidence. This practical, approachable guide turns gauge, yardage, shaping, and resizing into straightforward arithmetic you can actually use. Learn what gauge really means and how to adjust when yours does not match the pattern. Substitute yarns without fear of running short. Resize garments for a better fit by adjusting length, shaping, and edgings with intention. Whether you are modifying a neckline, distributing increases evenly, or recalculating yardage for a different weight of yarn, this book shows you how. Clear explanations and step-by-step examples make the math manageable, even if numbers are not your favorite part of knitting. If you want more freedom in your pattern choices and better fitting finished pieces, this is the book that gets you there.
