The bulk of this book was originally published in 1976. Since then, the author/creator/designer/technician has created 116 more mosaic designs which are (gasp!) rotationally symmetrical. Barbara Walker never ceases to amaze. For those not familiar with mosaic knitting, it is a method of two-color knitting in which you need to deal with only one color per row; you'll need to know only how to knit (sometimes purl) and slip a stitch. In the author's words, mosaic knitting is a "beginner's paradise." The first chapter contains instructions for reading the charts, and once you've mastered that, you can sail on through the charted designs.
