Having crocheted for a few years, and having learned to knit from Stitch 'n Bitch Knitting, I was excited to see what Debbie Stoller had to offer the world in the way of crochet. This book has some nice patterns, which is why I went out and purchased it. The instructions are clear and, as with her other books, cute and fun.
However, if you're a lefty looking to learn to crochet, there is NO WAY you could learn to crochet from this book. Don't even try.
The one(!!) sentence of instructions for lefties says it all. On p.27, the instructions tell lefties to either learn to crochet right-handed (which seems like a real cop-out on her part and, frankly, irresponsible) or "reverse everything - and I mean everything - in this book." And that's it. No other instructions, tips, NOTHING. Learning to crochet with your right hand would be equivalent to learning to write with your right hand: not easy and not necessary. There are other books out there that actually show left-handed instructions, diagrams, and tips on how to convert patterns for lefties. This book has none of these.
If you already know how to crochet, this book has some cute patterns (do check for errata on the website) but lefties are on their own. If you're looking to learn crochet AND you are left handed, my recommendation is to look elsewhere and (possibly) come back to this book when you've got way more experience.
