Wool

A series which encourages readers to take a closer look at some of the products which they see and use every day, by making collections, observations, and trying simple activities. How does a woollen jumper keep you warm? Where does angora wool come from? This book tells you how the wool from a sheep is made into a jumper. It explains how to tell the difference between wool and man-made fibres and has lots of ideas for things to do, including weaving and dyeing wool.
