Does anyone know of a good one?
I've never made a Thomas cake but I used these directions to make a face for James the Train:
For the cake I mimiced these instructions:
click on cake assembly and decorating instructions on this site http://www.thomasstation.com/misc/cake/index.htm
You may be able to get everything you need from the first link, but I had already practiced with the second one so I would know how big to make the face.
I just wanted to thank you both, one for posting the question the other for providing 2 great resources. This was just what I was looking for today!
