I have been asked to make a cake similar to this but have no idea of how they have done the "bubbles" covering the sides. Does anyone have any ideas? Also, any idea of how I determine the number of "bubbles" I will need and how long it will take to make enough to cover 2 tiers probably 9" & 6". Thanks for your help!
