I’m not sure what the collective noun for a series of decorative plates is, but I feel it should be a clatter of platters! Especially since the arrangement of which was not an entirely noiseless affair! We recently helped a client produce an alternative to the conventional headboard for their newly refurbished guest room. Having sourced a few additions to their previous assortment of china platters, we set about first scattering them on the bed, then aligning, arranging and re-arranging them until a pleasing disorder had been made from the chaos, and our trusted art hanger (with a steady hand) could hang them in place. I think it turned out rather well!
