This is no ordinary `all-you-can-do-is-read-it' book. Each copy comes with five feet of nylon cord and each of the 25 knots can be practiced right there on the premises: tied through the die-cut holes that accompany each of the illustrations. It's knot-tying for the landlubber, an absolutely foolproof connect-the-dots system that creates an entertaining book as well as a practical tool. When our youngest son discovered this book, he spent night after night in bed tying knots. We couldn't stop him! He now knows how to tie numerous kinds of knots and he loved learning.
