One of those hostess tricks I picked up at Judy's house: new Emma Bridgewater melamine cups at the bathroom sink. Judy explained that she was tired of breaking glasses--they do tend to slip from soapy hands, and shatter on the tile floor. I've long admired Bridgewater's simple shapes and the bold lettering with which she adorns them. Melamine, by the way, seems to be making a comeback--it was so popular in the fifties and sixties that people thought it would replace ceramic. Hardly. But I've been seeing lots of attractive plates and platters made of this resin; the Portland collection, printed with trees seen in the Oregon area, sold through the New York Botanical Garden gift shop, is particularly handsome.
