Architectural Digest has named it cathedral core: stained glass, moved out of the church and into the home. Designers are fitting it into bathroom windows, hallways and front gates. The reasoning is part nostalgia, part reaction. In a year when everything seems generated, people want something made by hand, the same way it was made centuries ago. Most of us are not about to re-glaze the hallway. Luckily the trend scales down. Amber tumblers, green carafes, a pink vase that catches the light at four o’clock. Here is what we’re buying.
