Here is the cake as it was carried into the venue. It all fit on one large baking tray, making it easy for me to carry it. The baking tray is lined with a rubber, no-skid material (sometimes referred to as shelf liner ... can be purchased at any Dollar Store or Walmart), to prevent the cakes from sliding around during transport. Notice the supporting dowel rods are already in the cakes.
Once inside, I stacked the three tiers. Since the dowel rods were already in place, it was a simple matter of just setting each tier in place:
Wrapping the ribbon around the base of each tier took just a couple of minutes.
Then it became a simple matter of applying the daisies, which were made from fondant ahead of time in the shop, around the cake. From the time I walked into the venue to the time I walked out (which included unpacking my cake tools, clean up, and then packing up again) was around 15 minutes.
