I have been given free reighn on a birthday cake for a 40 year old man, the only info on him I have is that he directs the disney on ice show & is a super fun guy. They want a tiered cake so I was thinking about doing diamiond shaped tiers (since I have the pans but have never had someonre order that shape!) I was also considering mixing shapes, had anyone mixed shapes with diamonds? Which shapes look good? Also since I've never done diamonds before I'm not positive what design styles look best. Any thoughts?
