What makes Kaffe Fassett's books so inspiring is his use of colour, his 'go for it!' attitude and his passion for knitting. Although this is a little dated from the style point of view - lots of 80s shapes - it is still a worthy addition to any knitter's library.
The patterns are easy to follow - he doesn't go in for complicated intarsia, virtually all designs are only two colours a row although they may look way more difficult, and there is a lot of 'nuts and bolts' information for inexperienced knitters. As long as you can cast on, do stocking stitch, and cast off then you'll be able to complete these patterns. The charts are excellent - good for using in other (more modern!) shaped designs and this is why I think his book is still relevant today. His designs, whether delicious poppies in twenty colours, or zig zag stripes, or huge damask flowers, have not dated - buy this book along with Ann Budd's 'A Knitter's Handy Book of Sweater Patterns' (or use your own favourite basic shape patterns) and create something unique and wonderful!
