Begin by wiring the plugs to each color cord, leaving one end free to string the hat and other components onto the cord.
Next, cut small holes in the top of a hat. Be sure that the holes are just barely large enough to fit the color cord.
String copper piping, hat, cord grip, and socket onto the cord (in that order).
Next, wrap an assortment of colored cotton embroidery thread around the Color Cord closest (to the top of the hat). This not only adds an extra pop of color or pattern, but it is also useful to cover up any areas where the fabric has moved away from the rest of the cord.
Gently screw in your bulb.
