It often helps to spend some time thinking about what you hope to achieve with the project prior to assembling the elements.

You should consider the guest of honor’s favorite activities, music, movies, television programs, sports, etc. Also, you might consider using a theme to drive the project such as tennis, classic tv, pop icons, etc. If your party already has a theme, then your montage should incorporate that theme. This works out really well as it reinforces the theme of the party and fits in with the festivities wonderfully.
