For 6 in. cake top, shape and position a 1 1/2 in. x 1 in. mound of black fondant. Attach leaves to mound with damp brush, overlapping to create flame look. Starting at the top edge of each side panel on 6 in. cake, attach your first batch of leaves with piping gel. Overlap and shape leaves slightly to create a wave effect. Support leaves with facial tissue, if needed to hold shape. Continue making and attaching batches of leaves as above, continuing down to base board.
