This book has a basic recipe for cardigans. You chose the collor shape, the sleeve top shape, the yarn weight. You follow the schemeatic or the recipe based on the number of stitches per inch yarn gauge you are using and plug in the number. I LOVE THIS BOOK!!! It has cardigans, pullovers, vests, tunics, coats, hats, mitten, socks, etc. for child small to adult extra large +. You decide which item, which, size, which yarn gauge you are using and it tell you how much yarn and what numbers to plug into the pattern/recipe. It ROCKS!!!
The listed price of the book is $29.95 - WELL WORTH the money!
