The document provides instructions for creating a mobile phone sock from an old sock to protect a phone from scratches. The instructions specify that you will need a sock, scissors, needles, and thread. You cut the heel of the sock, sew the left and right sides together with a cross-stitch to hold it in place, then turn it inside out so the sock covers the phone. Following the steps allows you to make your own phone sock instead of purchasing one for £1.50.
