I did this zebra with pink and green graduation cake for my cousin's daughter. I used electric pink and electric green gel colors. I used a shot glass to form the shape of the cap.
I was kind of in love with my zebra pattern. LOL. The top tier was only 4 inches so I had a hard time with fitting her name on it. I haven't mastered piping names so I made strands of fondant and shaped them and let them dry.
