Measure your foot jewel size and cut out 1 strand of thread double the size of your foot jewel + 2 inches extra. Similarly cut another strand of thread. You will have to fold the threads into half for beading.
Make jump rings using craft wire. Insert both strands into a jump ring by keeping equal amount of threads on both sides of the jump ring. Tie a knot on the threads with the jump ring as you can see in the picture.
Attach a needle on the other end (open end) of the thread.
Start inserting beads into the thread through the needle.
Keep beading until it reaches the required length.
Tie 2 tight knots with both threads and attach a jump ring at that end. Apply a drop of glue to secure the knot.
Attach an 'S' hook with a jump ring and some extra chains with the other jump ring. Done!
