In this instructable I'll describe how I made the carriage out of white chocolate. I used fondant to create the cobble stone effect. Then I piped in the white to fill in the gaps.
Step 1: Ingredients
The cake is a Chocolate Mud Cake covered with buttercream and fondant.
Approx 1200 grams of white chocolate buttons
I used the Wilton 16cm Ball Pan as a mold to help create the ball shape of the carriage. Any good cake decorating shop should carry the Wilton range, or you can order online. Make sure its the smooth ball and not the larger one with soccer ball pattern pressed into it.
I used the rings that come with the Wilton Ball Pan as the template for the wheels.
Pink Cachous for decorating the carriage. These are the small balls you can get in any baking section of a supermarket.
You will need piping bags to help pipe the chocolate in places. We made our own ones as we needed a smaller hole for most of the work. Look at this page for info on making them http://www.the-wedding-information-site.com/paper-piping-bag.html
You may find the chocolate will harden whilst in the piping bag. Just place them in the microwave for 5 - 10 seconds to soften them up, so they can be used again.
