Some easy centerpiece ideas for graduation parties include stacks of books, a piggy bank, a graduation cap or a photo collage. To create the book centerpiece, simply choose some old books, cover them in bright gift wrap and decorate the sides with rubber stamps.
The piggy bank centerpiece doubles as a way for the graduating student to earn some college funds and advice, as guests can deposit gifts or notes. Leave markers near the graduation cap centerpiece so guests can write messages and congratulate the graduate. For a collage, add photos that show the graduate in all stages of life to a large frame.
