I've definitely been putting "Cake Club-" in front of mine.
So a competition that I entered way back when I was quite green, I probably lost first place to because of the way my cake was presented, not the cake itself. The table needed to be pretty too! I did take some satin fabric with me, but I just didn't have the eye for it, nor the skills to fancy up the table.
So ever since then, I am so critical of cake boards and whatever immediately surrounds the cake. Sometimes it's as simple as just a fondant covering and a piece of ribbon, but it really really finishes the presentation, no matter how simple the cake may be. I think of it like an arrangement of flowers in a clear vase. If the blooms on top are gorgeous are pretty, then take the time to trim the stems and dump out the dirty water before you call it done.
I truly believe cakes finished all the way like that warrant an extra bump in what a person charges. Uniformity when it's called for, and an all around polished look is what counts in my book-decorations rate second.
So get ready to hear it repeated: no aluminum foil! Cover those boards! Wrap that edge with ribbon!
