First time with a topsy turvy cake (besides doing the practice cake--which turned out easier to do than this!). Also, first time using Isomalt. I made the diamond 5 times between isomalt and venuance pearls and this was the best out of all of them although the color was a little off and there were still bubbles. Cakes were nothing special, bride likes it plain, so they are yellow and 'funfetti' with vanilla buttercream and fondant accents. Ring is gumpaste painted with a silver luster dust/vodka mix. Even though the bottom tier collapsed and I made another 3 layers late at night, I was very happy with the result of this being my first. I hope to try it again, and have it be much better!! TFL!
