This book does not have 45 hats in it, it has 9 hats (berets, toques, cones, stars, Egyptian hats, onion domes, stacked hats, Angela hats - like toques with long rectangular straps hanging from the crown, and pentagons) interpreted in several different color designs each. Although the cost of this book was many times the price of a single pattern, I bought the book because I couldn't find a single onion dome pattern. Well, the "patterns" are really just color charts for the designs she used. Sample instructions for the onion dome hat (instructions are the same for all 5 onion dome hats): "Cast on the number of stitches indicated on the chart using a 16" circular needle....Work the desired band....Follow the chart for the bottom of the hat. Repeat the band. Work the top chart...when you finish the chart, change to the color you want for the ball [pompom or tassel]...then make the ball as instructed on page 11." This is not what I consider a knitting pattern and I'm sending it back to Amazon.com in Monday's mail.
