It is believed that man has been using wool for about 10,000 years, i.e. from the time when he domesticated the sheep. First, fur was used, and then fleece was processed using the felting method. The processing of wool using the spinning method developed in 400 BC. in Babylon, and it had its peak when the merino sheep was delivered to Rome. After that the export of merino sheep to all continents begins. Wool has great importance and is used for various purposes; insulating material, fertilizer and raw material in the fashion, pharmaceutical and cosmetic industry. Some of the largest producers of wool in the world are namely China, Australia, New Zealand, Turkey, etc. In Croatia, production is very modest, and wool mostly represents an ecological problem, and most sheep breeders do not see its benefit and consider it waste. This final paper tries to show wool as a useful raw material that should not represent waste to sheep breeders, but an important product that should be utilized. Although our autochthonous breeds produce coarse wool of poor quality, this wool can be used to make blankets, shoes, mattresses, carpets and other coarser items. With the financial assistance of the state and the will of growers, wool can be of great economic importance and one of the sources of income.
