Everything is edible. Bottom cake is made of 2 8" rounds and a 7" round in the middle to give it a tapered shape. Tea pot cake is made from the Wilton ball pan mold. The tea cups are all gum paste that I molded in a martini glass. The letters are funky letter tapits. The roses, tulips, leaves and baby's breath are all gum paste. Buttons and fabric doilies are all gum paste as well.
