Bay seniors ready to turn nature into art this holiday might want to check out the wreath making class this Saturday at the San Francisco Botanical Garden. We’re not just talking traditional pine branches and cones but the trendier succulents and even local mosses and lichens. Since they are cuttings, when the last drop of egg nog is poured, you can pot them for your garden this spring. Classes from 9-12 and then 1-4. $45 for non-members.
