These decorations are made with fondant. Flowers and white needles are made with royal icing. I use bamboo stick and floral wire inside. An order comes with 3 pieces ( one of each kind). Approximately 1 inch height on a round cactus, approximately 1 1/2 inches height on a cactus with white needles and approximately 3 inches height on a tall cactus. Made to order, so each may vary. Please allow 1 week before shipping. Custom order available. Please contact me through Etsy.
