Use tip 2 and white icing to pipe lines about 1 in. apart beginning about ó in. inside the top edge of cake and extending to various lengths down cake sides. Use tip 3 and white icing to randomly pipe dots on either side of lines.
Attach roses to top of cake with icing. Use tip 18 and white icing to pipe shell bottom border.
Attach drop flowers to shell border. Use tip 352 and green icing to pipe leaves.
