The book starts with a short history of hats and their varied forms, followed by a fairly brief basic technique section.This book is clearly laid out with detailed patterns and clear photographs of all the projects and is divided into sections for, basic shapes,cables ,lace, colour and embellishments,each pattern is also given a star rating for difficulty. At the end of the book is a useful abbreviation section, explaining the various stitches.There lots of lovely, fun of hats in here, many perhaps suited to the knitter with some experience, though if you are new to knitting with colours, the instructions and concisely laid out patterns, featuring the graph method would be a good place to start.There are several patterns using only two colours which produce a great looking original and stylish way to keep your ears warm. The cabled patterns provide more of a challenge, many using quite complex patterns with detailed charts, patience and experience are required for some of them.My personal tastes don't run to embellishments so much, there are some slightly crazy offerings here, a large knitted "flower "stitched to the side of a plain hat, however thats just my taste ! the other lovely fairisle and slightly Nordic influenced patterns more than make up for the few I would never knit. However please don't be put off if you are a beginner there are some great shapes for headgear in here easily adaptable to suit your capabilities. Learning to use circular or four/five needles (my preferred method )makes hat knitting easier and neater.
