Most clothing appears to have been made of animal skins, as indicated by finds of large numbers of bone and antler pins which are ideal for fastening leather. Wool cloth and linen might have become available during the later Neolithic, as suggested by finds of perforated stones which (depending on size) may have served as spindle whorls or loom weights. The clothing worn in the Neolithic Age might be similar to that worn by Otzi the Iceman, although he was not Neolithic (since he belonged to the later Copper age).
