Discussion here on the clash of various Advent purples. Maybe part of the problem is trying to match up paraments and other such things with vestments. The only “requirement” for purple is for clergy wear. Not church decorations, necessarily. Having a wider palate that includes blue, rose, silver, white, and maybe even black might not be a bad idea.
In my new parish, the Advent wreath isn’t huge like I’ve experienced in other places, but it is thoroughly decorated. I usually like large and simple, but combination of bulbs, feathers, and such seems reminiscent of central European Advent wreaths–charming.
