This document provides instructions for making a mobile phone cover out of a sock. It lists the necessary materials as socks, cotton, needles, and scissors. The steps involve cutting off the heel of the sock, sewing the sides together to form a cross-shape that will hold the phone, and then turning the sock inside out so the sewing is hidden and the sock forms a protective phone cover. It encourages ensuring all needed materials are gathered so the homemade phone socks can be of high quality.
