This Amy’s fourth book on sweaters, and at this point its pretty fair to ask why she wanted to write another sweater book!

Her Ultimate Sweater Book is designed to be a comprehensive, everything-you-need-to-know reference for designing and modifying sweater patterns. Need some detail about fibers and fabric? Drop-shoulder formulas? Modifying an hourglass pattern into an a-line one? Adding a pocket? Whatever else you might be thinking of?

Amy’s got you covered.
