Pastillage is a sort of medium like gumpaste but only stronger. It is made with gelatin, water, and powdered sugar. The recipe I use is in the cake bible. The cake is covered in fondant and that is why it looks so smooth. Do you think I could get a buttercream that smooth? No way! It really only took me one night and part of a day to do. Fondant is so fast. The bows had to dry overnight and the cocoa painting was done ahead of time. The rest was done right on the cake with food markers and air brush coloring (dries faster). The board was covered in fondant.
I had meant to only post in the contest. I asked for the site moderator to delete the other post.
