Practical Knitting Calculations Made Simple

Math for Knitters by Kate Atherley is a focused reference for knitters who want more control over their projects — whether that means working with a yarn that doesn’t match the pattern gauge, substituting a discontinued yarn, or adjusting a garment to fit a specific body. Atherley is a Toronto-based knitting author and teacher with ten books to her name, and she approaches the material the same way she does her sold-out classes: breaking complex concepts into clear, manageable steps.

The book covers four core areas:

• Gauge — what it actually means and how to work with it when yours doesn’t match
• Yarn substitution — calculating yardage, converting measurements, avoiding shortfalls
• Pattern customization — modifying for fit and style, and knowing when to choose a different pattern instead
• Garment alterations — adjusting length, shaping, and sizing without complex calculations
