This is a new book (2006) by the Yarn Harlot (Stephanie Pearl-McPhee). True to form, she writes in an entertaining manner and gets a lot of chuckles out of me. There are lots of fun and useful tips, peppered with funny comments. What I found the most useful was her section on beanies and how to do the pattern on your own "The No Pattern Hat". I have used the ideas in this chapter on multiple occasions and now I can successfully measure a person and knit a perfectly fitting hat for him/her.
This is a fun book and would make a good gift for your favourite knitter.
