When the manipulator fits a hand into the closed end of the sock, the puppet can be seemingly made to "talk". The puppet''s mouth is formed by the region between the sock''s heel and toe, with the puppeteer''s thumb forming a jaw. At a minimum the shape of the hand will instantly form the shape of a mouth, but sometimes the mouth is padded by putting in a fairly hard piece of felt (often with a tongue glued inside). The sock is stretched out fully so that it is long enough to cover the puppeteer''s wrist and part of the arm. Often, but not always, the puppeteer will hide behind a stand and raise up his or her hand above the stand so that only the puppet is visible. Many sock puppeteers, however, stand in full view along with their puppets and will hold conversations with their own sock puppets, using ventriloquism.
