At these events the focus is on creating something with one's own hands, the most beautiful side effect being that this can often be combined with a charitable purpose. Guided by regional craftsmen, individual pieces are created in small construction teams. A bee hotel and a feeding trough or wooden toys are conceivable. Depending on the project, the material is glued, strutted, cut, joined, sawn and drilled - a wide variety of materials are used and ultimately form the whole. After completion, the building object is either taken home for the owner's use or officially handed over, for example, to kindergartens, clubs or communities - during a common party at the end.
