This book includes the child and adult size, as well as using the 36 and 41 peg Knifty Knitter looms as well as other options similar, like Darice and Boye looms. I also include the 44 and 59 peg 1/2 gauge CinDwood looms, with the option of being able to put together looms with same peg count using Martha Stewart looms. Each of the new patterns comes with a private video tutorial, along with the written. It offers an array of sizing, looms, learning styles, and difficulty levels.
