I have a joy of making fun 3-D birthday cakes. We (yes- we!) started making these last year for my sister's birthday and have since then done a cake for my brother-in-law and just did one for my niece's birthday. This first one is a dragon we made for my sister.
I got this "recipe" online. Theres is way less messy, but hey- it was our first 3-D cake. We've learned lots since then!
