The previous day, the team begins by putting together the "cage" of the house with slender sticks of the Madrone tree and red vines. Once the cage is in place, the straw is chopped up. Once the pasture grass is shredded, it is moistened and spread out over a mud and clay soil, to later be mixed together. At this point the men form a human chain by linking their forearms and stomp on the mixture, adding water until the mud and clay become solid.

Then those with the most experience are put in charge of kicking out the first lump of clay, with which, little by little, the work team forms the walls of the thatch hut.
