Made to welcome a friend's new baby. Took much longer than I thought. I had covered the cakes in fondant and put them in the fridge overnight and I must say that it helped when it was sweating to put the waves on. Very time consuming. Basically ribbons on fondant were applied from top to bottom. They were applied straight & then sections pulled out & parts glued to the cake. This is a 10 & 8" cake. Fun to do. I'm not sure where I got the bubble idea in the waves but I loved it when I saw it & did it here.
