The kit contains a book with the patterns for 12 Star Wars characters - Boba Fett, C-3PO, Chewbacca, Darth Vader, Wicket the Ewok, Han Solo, Jabba the Hutt, Luke Skywalker (Jedi), Princess Leia, R2-D2, Stormtrooper and Yoda - as well as the yarn, hook and eyes to make Yoda and the Stormtrooper.
The kit is published by Thunder Bay in the US, you can find it listed on Amazon, although it will be available in other stores. It's also due to be published shortly in Australia/New Zealand by Hardie Grant under their Chirpy Bird imprint. Hopefully it will be released in other countries too, but there's no information about that at the moment. It is listed on Amazon UK though, due out in May.
It's really exciting to see my patterns made into a book like this. I love the photographs of the characters, mixed with stills from the films in the book, and it was wonderful to be told that Lucasfilm were thrilled with the way the book came out!
