i made this for my nephew. the rectangle cake is a 9x13. she wanted the cake to be in fourths w/ those colors for each fourth. the smash cake was tweety bird that i just drew free-handed w/ icing. i wish the lines dividing the colors were straighter and the sides of the cake were better. i used icing in a can for the sides and it was melting in the louisiana heat. everyone loved it and it tasted yummy though so that's good!
