I have made a few graduation cards. I created the sentiments in Adobe Illustrator.
This first card opens on the back. Inside is an envelope of sorts that the grad pulls open and . . . . you'll see the instructions in the second photo.
This card is a shaker card. Fortunately, the graduate receiving this card will not have to clean up the confetti.
The rest of the cards are pretty classic. Happy 2020 Graduation.
