Step 6: Edges and corners of your Cubecakes
To make the corners cut out 3 small triangles and pinch them into a tetrahedron(without a bottom) and stick it to the cube.
Then add a small square of fondant in the between the corners.
Lastly make a small sphere and smush(very technical term) it to the face of the cube
Repeat until all edges, corners, and faces have been done.
