What graduation is it? Grade School? High School? College?
You could do luminaries.. white bags with a printed design that you stick onto them, then a little sand and a candle.
Custom Candy Bar wrappers are always a hit and fun decorations.
I've done empty quart paint cans, covered with custom label and then photo bouquets in them... pictures on cardstock attached to various size sticks and some raffia for fluff.
Is it at your house? or being held somewhere? If at your house, would be fun to do a slideshow DVD of pics from her life that could just run and loop on the TV.
Hope some of these ideas help... I can always help find more!
