Gigi also has a website where kids can join the "Gigi's kindness corps" and knit for those in need. Her website also includes videos of instructions to get to "the next step" so to speak. The videos explain the purl stitch, different cast-on methods, and techniques of finishing. By the time a young knitter has finished the projects in the book and watched and learned the information in the videos, they will be ready to go further into the knitting world.
I want to point out a wonderful thing that Gigi (who speaks in verse) has said: "Practice makes perfect will never apply. We all make mistakes, no matter how hard we try. So be of good cheer and do not despair. With time and some care you'll have something to wear." Every young knitter should hear this--and experienced ones, too!
Recommendation: boys and girls ages 6+. Adults could learn to knit with their kids with this book too! --Haleyknitz
