We didn't used to own a set of Santa Claus salt-and-pepper shakers or a Frosty the Snowman slushy maker, but we do now, thanks to Zinnias at Melrose, our favorite spot in town for vintage holiday gewgaws and all things Christmas. There, we've seen boxes of 60-year-old Shiny Brite glass tree ornaments stacked alongside mint-in-package tinsel, bags of still-glossy garland strings, and even an ancient card full of brightly painted jingle bells. We bought as much as we could and dragged it all ho-ho-home. Next time we were back at Zinnias, there was even more Christmas stuff, right where we couldn't miss it, just inside the door. It's remained there, year-round — well, most of it, anyway. We keep going back and buying more red-and-green holiday stuff from the '50s and '60s. And you can, too.
