My daughter recieved this book as a 7th birthday present. I am not a very skilled knitter - learned how to do it as a child, but hadn't knitted a stitch for about 20 years, but I found this book really clear,well-presented and easy to follow and I found it easy to help my daughter learn to knit. (It even explained very clearly how to use the french knitting kit she'd been given for her previous birthday which we'd given up on after trying many times to understand the instructions!)
It has various simple projects for things like animals, toys and knitted flags, and each new project teaches a new skill, but your child can make things from the first pages. The book is also very attractively laid out. It makes a nice present for a child (I'd say 7-10 would be the right age group), but might also be helpful for an adult novice knitter as the instructions are so straightforward.
