Hi - I just recently did 4 grad cakes and got lots of great ideas from this site. 3 of the 4 were 1/2 sheet cakes. I used the small pampered chef batter bowl to make the cap. On one of the cakes, I put edible images of the school logos. They looked really sharp. I also have made a diploma - either rolled up or unrolled. On one cake, I incorporated not only the high school the person was graduating from, but the college they would be attending. Good luck and definitely look in the gallery! All these creative people here will give you lots of ideas!
