I usually have people pick up their cakes the day of the event, but this weekend the person wants to pick it up the day before. I am a worry wart because I've seen so many pictures of cakes that fell over or whatever. The cake is a 10 inch bottom and 7 inch top... i will be using the poly sticks for support and will drive a wooden dowel down the center. Am I worrying for nothing??? Please tell me that it should be ok.
Properly doweled it shouldn't be a problem. Are you doing buttercream or fondant?
It should be OK.
PS Can I introduce you to SPS?
I'm sure you'll be fine. I just did a 6"/8" stacked anniversary cake that had a soft buttercream (more butter to shortening ratio) which i was worried about and heavy gumpaste/fondant flowers cascading down the front. I completely decorated it Sunday and stored in my fridge till it was picked up Monday evening. It was fine and the daughter even carried it in her lap on the way home which was about 30 mins away!
I covered the cakes in buttercream (indydebi's buttercream recipe) and MMF.
It should be fine. Sounds like you've covered your bases. The only thing I can suggest is that you purchase some rubberized shelf paper and give a large piece to the client with instructions to lay that on a FLAT floor in the car, then put the cake on top. Also put a piece of rubberized shelf paper under the cake in the cake box. It will not move unless they drive too fast.
p.s. I recently used SPS for the first time. I wrote Leah_S a personal thank you! The SPS system is wonderful!
I have to chime in on the SPS No fail with that method!
