Not a standard pattern book, this is a complete recipe for making your own custom-fit hats, for any head, with any yarn. Just grab a skein and start knitting. With instructions for slouchy and beanie-style hats, and tutorials added for decorative flourishes like different cuff finishes and pom-poms and tassels, this book has everything you’ll ever need to keep everyone in your family warm.

The recipe includes all the instructions and numbers for three styles of hat with three choices of cuff, in 13 gauges and 17 sizes, covering preemies to XL adult heads. And if those don’t cover your needs, the formulas are included so you can calculate your own.

The book steps you through the whole process: from choosing yarn and determining size right through to finishing, with tutorials for all the key knitting techniques – casting on, working in the round, stretchy and decorative bind-offs, even weaving in the ends. There’s a whole chapter with ideas and instructions for customizing the hat with colour, changing up the hem pattern and style, and adding decorative flourishes like pom-poms and tassels.

Don’t worry, a yardage table will help you make sure you’ve got enough yarn: and there’s lots of tips and tricks for what to do if you think you’re going to run out, and how to use up small quantities of yarn leftovers.

There’s even information on making hats for the most delicate of heads: premature babies, cancer patients and others losing their hair because of medical treatments.

Whether you’re a hat novice, or an experienced knitter of headwear, this book has something for you.

Photo tutorials and guidance on fit and yarn help you make your first hat perfect. For experienced hat knitters, the advice on customization and straightforward but powerful formulas empower you to get designing.
