As for the design, I coated the cake with white buttercream and decorated it with blue buttercream in a whimsical design. I couldn't get the right shade of blue which was the motif of the wedding as there was only 2 shades of blue coloring available at the bakery.
Working in a bakery with no air conditioner was a headache. No matter how I tried, it was impossible to keep the frosting in place so I had to redo it. That explains the smudge on the cake. The second time I did the design, I put it back in the freezer every time I finished piping. It helped! I ended up with sore arms and back though. Imagine lifting a 25 pound 3-tier cake all by yourself.
The newly weds with the cake. The ribbon tied around the cake base was the right shade. I know the wedding cake was far from perfect but doing it in a hot bakery with only few tools, limited supply of ingredients and no assistant at all has made me proud of my accomplishment.
