I am planning on making 1 or 2 swimmers for a 6" top tier swimming pool cake. I also want to have two legs sticking up like someone is doing a handstand. I've never done sculptures before, so how much of the toothpick do I need to stick into the cake to keep things standing up. The people may not even need toothpicks. They may be able to just be placed on the cake. I plan to use fondant with some gumpaste, so they should harden. I'm most curious about the legs. I don't want them to fall over. Should I use something else, like skewers or dowels? Not sure if I could find some short enough??? Thank you!
