Oh Boy.  THIS BOOK!  If there is one book to have in your knitting library, I suggest this one.  It's truly a gem of a book.  Absolutely everything a knitter needs to know is in here.  I mean everything!
It was first published in 1989, updated in 2002 and the past fifteen years have seen many advances in knitting which made it time for another update.  Sure, there is always the internet to look techniques up.  However, there is nothing like holding the information in your hand.  This book is easy to navigate with thorough indexing and footnote cross-referencing.
The updated Vogue Knitting contains:
•Expanded library of cast-ons, increases, decreases and bind-offs.
•In depth sections on brioche, enteric, double knitting and mosaic knitting.
•New design and construction chapters for accessories with dozens of options for hats, mittens, socks, gloves and more than 25 shawl shapes.
•Comprehensive chapters on lace and cables detailing all knitters need to know when increasing, decreasing, reading charts, working borders and much more.
•Revised and expanded information on tools, correcting errors, finishing, embellishing, and garment care to instill a masterly understanding of knitters at every stage.

My mother gave me the edition first published in 1989.  It has been my constant by my side.  I reference quite a few things out of this book.  From the most simple techniques to those used to design sweaters, helping me design the libby sweater back in 2009.  Truly a knitters bible.

Happy knitting, friends!
