Rita Maassen's easy-to-use system for interchanging the elements of basic sweater designs is genius and will have you making sweater after sweater to your own specifications. The book begins with six basic pullover designs, then the author explains her system for mixing the elements — necklines, armhole style, silhouette, colour and texture patterns — and gives you the instructions for each different design element. Finally, she puts her system into practice in 23 unique sweater designs, giving the full instructions for each. You may then either follow these patterns as written, or do your own mixing and matching to create your own unique sweater pattern. Over 70,000 different sweaters are possible with the options presented!
