Step 1: Materials
3. Duct tape!
4. A needle and thread
5. Sock with an ankle long enough to hold an iPhone (thinner fabric is better)
6. A square plastic bag
Step 2: Measuring and Cutting Your Sock
Step 3: Sewing the Sock Together
Basically, after threading the needle, you double the thread back on itself, and tie a knot about a foot away from the needle. Push the needle though both sides of the sock, and then repeat on the same side, about 2 millimeters over. When you get to the other side of the sock, tie another knot to keep the thread from coming undone. I also turned the sock inside out when I was done.
