josh blackwell‘s ‘plastic baskets’ series as part of an exhibition exploring the imaginative possibilities of detritus at the riverside art museum questions the nature of waste and necessity. the plastic bags have been salvaged from kitchen cupboards and city streets, embroidered with yarn and up-cycled into artworks reminiscent of ethnic basketry. the exhibition coincides with the banning of plastic bags in unincorporated areas of the county due to their detrimental effects on the environment. timely indeed.
