I made this cake for my nephew and I'm new to decorating cakes. I started at 7pm and was up till 3pm because I kept having to change the tips. I only had one tip and the directions called for me using the same tip over and over again so I had to keep changing it and re-washing it and I didnt prepare any of my icing and there was so many colors involved. All I can say is that I learned from my mistakes! I bought lots of extra tips!
