The two sides are attached by yellow ties.
Now here is the magical part: in one corner I sewed on four little symbols made of cotton cloth. Each symbol relates to one of the blanket's four magical functions. Green square = ground/center/shield. Yellow circle = mental clarity. Red triangle = heat. Blue teardrop = peace and calm. They basically work like buttons on a remote control: press one and think about its purpose, and it activates. The blanket recharges itself automatically from ambient energy.
