I really love the challenge that comes with a 3D cake.
You have to think about the physics and gravity issues to make sure your cake will remain stable enough for transport. I also try to use the minimal amount of internal structural support to ensure easy cutting and serving at the party.
There are a lot of tutorials out there on how to make a Thomas the Train cake. And you better believe I looked at a LOT of them! I find the best teachers are the ones out there blogging and sharing! Here is a REALLY good step by step tutorial
Also, finding pictures (or better yet a physical model) of what you want your final product to look like really helps! You have to use your artist's eye to think about dimension and proportions.
I found myself rushing to get to delivery so I didn't get the best pictures. But I hope you can see all the fun details.
Thanks for stopping by!
And if you don't mind .... know of any good tutorials to share?
