Their overall shape and the material from which they are made vary according to purpose.
Tung may be made of a succession of web-like forms made of threads woven round cross-shaped frames, or from single long pieces of cloth.
Bamboo strips woven horizontally represent steps guiding the deceased to heaven. The longer the tung are, the more beneficial they are thought to be.
Talaeo are much less common. Made from plaited strips of bamboo from five or seven points, they serve as a charm against evil spirits.
They are placed near entrances to houses or villages to prevent entry by the spirits of the dead.
Similar plaited shapes may be seen in rice fields protecting offerings to Mae Phosop, the goddess of rice, during the growing season.
