I'm not sure what this technique is called, but I've been calling it chocolate lace. I saw it once and recreated it. Pretty easy, you just have to time it just right. But, it's the chocolate drizzle swirls, wrapped around each tier. You just drizzle and allow to semi-set. Corresponding colored ribbon on each tier. Lavender colored rose bud on top with rose petals all down and around. It turned out really lovely.
