Kaffe Fassett is an artist using textiles (knits, quilts, needlepoint) and paint. His style is to use a sort of ornamentation-on-steroids, a wild profusion of color and pattern to create a wash of color with pattern that looks logical in its confusion. His work never fails to amaze me. If you liked his earlier knit books, this Pattern Library is a really valuable addition. Instead of sweater patterns, this book has detailed charts of the designs and hints on how to knit them (such as the popular round Persian Poppy pattern that you can knit using a "magic ball" or random strands of yarn tied into a giant raggedy ball that yields fascinating results.) For those who design their own vests, pullovers, jumpers and coats, this is a really valuable reference book. Personally, I'd just use it to knit pillows and not even worry about creating a garment with the patterns. Plenty of color photos, detailed shots and a nice printing job, too. Highly recommended for knitters who love colorwork.
