Are you familiar with the Della Robbia Christmas wreaths made by Boys Republic in Chino Hills? They’ve been produced since 1923, an even 100 years. Curious about the wreaths, about which I’ve read yet knew little about, I visited the production barn last week to learn how they turn out 30,000 of these things and how this tradition got started. That story is told in my Sunday column. (As I joked to someone on my tour, I figured I’d better visit for the 100th anniversary, as I hope to be retired by the 150th.)
