Sodor Island Cake

This cake was made by placing two 11"x15" sheet cakes side by side, then carving it into the general shape of Sodor Island.  I carved them at an angle so the sides would look like gently sloped beaches.  I frosted the sides and areas under the lighthouses with sand-colored icing, then added the blue icing around the island, I pulled up on it with a spatula to make it look like water and waves.  I used some of the carved-off cake to build up hill sides on top of the cake.  The rest of the island was covered in green icing using the grass-tip.  The train track was piped on using the smooth side of a small basket-weave tip and brown icing, and a tip #3 and black icing.  The lighthouses, round house, castle, windmill, trains and helicopter were all hand-sculpted from marshmallow fondant.  The trains were about 1-inch in length.
