I've been around on the web for over five years now and I get asked a lot of "can you make this?" and the answer is always "YES!" As long as I have an image, I can make it (and sometimes I'll make the image up as well.)
Here is a Lego® Cake Topper I was recently commissioned to make:
And a Chibi-style cake topper:
And lastly an adorable Phoenix and Dragon Topper.
So if you are trolling around for topper or sculpture ideas and can't find what you are looking for, drop me an email. I enjoy a challenge!
