I have to reply bc I just learned a few weeks ago myself. KIDS KNITTING by Melanie Falick. Yes, its written for kids, yes the illustrations are bold, bright, clear. They do not assume you know anything! I love this book. I had gotten a few others, like Knitting for dummies or st, but I guess I was too big of a dummy even for that one, lol! Seriously this book is great!
btw I just got it from the library, which is what I would reccomend until you're sure you'll like it.
Knitting is a lot of fun, I just finished a two color hat with tassles, and scarf with pockets set for dd. Its very cute if I do say so myself.
