After purchasing this book, I took it upon myself to look up any errata on this book. Sure enough, I found one. Little did I know that there would be more of these. I started working on the origami heel and found the instructions confusing. I had to rip several times and then later found out that there was an errata on the origami heel instructions for the first Socks a La Carte book (Part I). I don't understand why the editors did not correct the second version when they posted the errata on the first version.
Do not buy this book especially if you're a beginner. I am an experienced sock knitter and I think this book is full of mistakes.
