Thank you everyone for your help, I have to say that I should have said no to even trying the stand up drum. I need to know my limits. I wanted a challenge and I tried... and FAILED. I started at great, I was happy it looked good, but the heat made the buttercream slide down and the fondant deco on the front on the drum started to slide bringing more butter cream down, I removed the deco, refrosted, and was going to put the deco back on at the last minute but this stand up drum was doomed. One hour before hand I removed icing, flipped it back on its side, * added the cut out portions to help it stand back to the cakes and made this a flat laying drum. I didnt even get a cell phone photo in the rush, and arrived 15 minutes after the party started. I so wanted to thrown in the towel , throw it in the trash and go buy one for her. I was able to pull off getting something presentable but not my norm and not what we both initially wanted,
My friend was so patient, and nice, I have to make this up to her someday.
My advise .. Dont try it. I did see somewhere where they did it with 1/2 the cake ( and the bottom half styrofoam)
If I am ever crazy enough to try again that is what I would try.
Days like to day really make mu AWE over all those awesome cakes here
...think I need a cake break..
