Toppers can be based on mutual interests or professions as well.
If the bride and groom are both doctors then you might make a figurine in which they both are in between a stethoscope with one end of stethoscope in bride’s ear and the other in groom’s ear. If the bride is a nurse and groom is a doctor then you might like a figurine in respective professional dresses and holding all the tools for an operation and standing in front of miniature cake.
Although it is easy to find the profession of the couple but more effort would be needed to find wedding cake toppers that really highlight that one thing that they both love. Toppers based on the mutual interests of the couple can be on their hobbies like sports e.g. badminton, swimming or dancing, travelling or a character of their favorite novel, movie or a story. If the couple likes traveling then maps, binoculars and ships can be part of small meaningful miniatures. The toppers can also be based on the recent activities of the newlywed couple. It can be a miniature of a bride and a groom in sports car or any models which they have bought recently.
