After I've made the base of my figure how do I cover it with fondant?
Do i do one blanket piece and then add on details?... or do i have to put on icing and then put on the fondant...
I just took a class this past weekend with RKT modeling and we just put the fondant directly over the RKT figure. We rolled the fondant thick so it would cover all the bumpy surfaces.
It can and is done lots of ways. Some people use melted chocolate first, some ganache first, some with BC first and some with nothing.
Personally I try to pack the RKT tight first, then use BC and a thicker than normally piece of fondant to cover. The BC helps it adhere to the RKT and helps fill in the cracks (also makes the RKT tastier IMO) and the thicker fondant helps make if even smoother as mlwideman stated.
I use royal icing to adhere my fondant to my RKT.
