First cut a small piece of fabric then cut to small holes in the middle. Take some string and feed it through these hole and tie it. A bowline knot works well.
Step 2: Add cotton balls and LEDs
Make some LED throwies minus the magnets. Insert LEDs through the two top holes or just add cotton balls.
Insert an LED so that it will face the bottom of the ghost.
Step 3: Positon ghost's neck
Position the ghosts neck so the bottom LED is just sticking out. This will illuminate the body of your ghost.
Step 4: Tie the neck of your ghost
You could use any knot for this part, but I recomend a constrictor knot. First take a piece of string and place it across your ghost's neck. Then take the right hand end and loop it around the ghost underneath the other end. Then place your thumb over the loop and loop around again, but this time over the top. Take the working end and tuck it under where your thumb is. Now take the working end and pull it through the bottom loop.
