The Nor-Cal Insulator Club patch is in the shape of a CD 120.  It has a dark blue border and an aqua background.  In white thread, "NOR-CAL" is sewn in an arc at the top, "INSULATOR" is sewn vertically down the center, and "CLUB" is sewn across the bottom.  On the left skirt of the insulator, the letters "C.E.W." are sewn with an aqua colored thread.  Some dark blue thread is also used to suggest wire groove ridges.  The patch is 2-3/8 inches wide at the base, 2-1/4 inches wide at the wire ridges, and 4 tall.
