Year: The graduation year is an easy decorative touch: number balloons can be purchased to create the year, or graduation party supplies such as plates, cups, banners, confetti and more are available with the current year.
Consider the personalized winter coffee, snowflake bath confetti, Winter Wedding Cocoa Mix, silver spark snowflakes, winter chocolate take out boxes, silver kissing bells, and snowman snow globe favors.
Ripping a credit card offer in three or four pieces is NOT enough -- you need to create confetti, preferably marinated in coffee grinds and bacon grease, to repel a determined dumpster diver.
Add streamers, napkins, balloons, and candles in basic colors, or opt for more star-studded supplies such as glittery confetti or movie and music decorations without a specific theme.
Many such stores will have all of the balloons, streamers, confetti, and other accessories that you need, and they can be a good source of ideas as well.

General decorative: There are also stickers that serve as general decorative elements such as stars, flourishes, confetti or geometric shapes.
A small dusting with gold confetti on the page could add excitement or you could substitute the gold confetti for watercolor paint accents.
Scatter white snow and silver star-shaped confetti on top of a solid white, red or green tablecloth and your centerpiece will come to life.
If that doesn't fit with the rest of your theme, maybe a different celebratory image like confetti or streamers would be appropriate.
