A well-crafted artefact is signed by the maker. Not literally, but the artefact subtly tells the audience who the maker is.
The maker’s attitude towards making, the situation they made it in, and their way of working can all be reflected in the artefact. Subtle details the maker feels strongly about.
Often the maker and the designer of the artefact are the same person. If not, the designer often has a hand in making it. When designer and maker are close, or the same, this sense of identity in the finished artefact is even stronger.
