In Europe and North America, snowmen are built with three spheres depicting the head, torso, and lower body. Snowmen are usually built with two spheres in East Asia and one or two in Japan.
The perfect time to make snowmen is usually in the afternoon. Snow becomes suitable for packing when it approaches its melting point and becomes moist and compact. This allows for the construction of a large snowball by simply rolling it, until it grows to the desired size.
