Here is the cake I made for Conor's first birthday, and the blog post about it: http://sarahdesigns.tumblr.com/post/60571369065/well-i-think-this-turned-out-well-its-my
This cake wasn't as difficult as expected, mainly because I didn't stand and do it in one go. I baked a few cakes and then stuck them together in the basic shape, then covered the whole thing in a layer of buttercream. I then left it to set and got on with something else. That evening I made the fimo bits and pieces, and the following morning I covered it with icing dyed with gel colours. It came together pretty well, because I wasn't rushing it the evening before, hehe! It's my favourite cake I think, I'd love one for me!
