Fiona Goble's book Knit Your Own Zombie is an interesting idea that seeks to get people who wouldn't normally knit interested in the past time and also giving veterans a unique way to delve deeper into their hobbies.
Knit Your Own Zombie provides you with eight interchangeable characters to choose from, allowing you to easily mix and match your creations. Fiona Goble's book also provides you with the important zombie accessories—brains and guts—that you'll need to keep your knitting monstrosities looking good. Follow the book and you'll be making your zombie cop in no time.
The current popularity of zombies is undeniable allowing for normally niche activities, like knitting, to gain attention by capitalizing on these global phenomenons. As long as they don't make a sparkling vampire knitting book I think I'll be okay.
