Once fiber structures provided shelter, served (as baskets) to carry food and (as boats) to carry people, shielded heads and sometimes covered the whole body; today they hang from the walls and rise from the floors of museums. The fiber art presented here is currently on view at the Carnegie Institute in Pittsburgh in connection with the biennial convention of the Handweavers' Guild of America. There are a few tapestries and other loom weaves, but most of the examples were produced by non-loom or off-loom techniques. They don't, however, resemble the dishmops you've seen displayed in some museums: these fiber artists are craftsmen, and Christine King's ""Tranquility,"" Carol Kurtz's ""Flight of Fancy"" are at once impeccable and expressive constructions--integrally expressive, that is, in the way of a Brancusi marble fish. The brief, pointed text fills in the historical and cultural background; the fiber structures--illustrated in color and black-and-white--represent ""the Aesthetic Continuum"" not only in the US but in Europe.
