I created the invitations on my computer. Had I given it more thought, and had more time, I would have asked for student volunteers to create cards.
For the gifts, I bought plain Hershey bars and created a new "wrapper" for them. I've seen this done for different occasions; birth announcements, wedding favors, etc. I had the hardest time finding the dimensions to make them the appropriate size, however. It took A LOT of trial and error (and paper!) until I finally got it right. You can download the template here. The poem was anonymous, and I found it on the web. I had some students help me wrap the candy bars during recess time and we even placed a few stickers on them to dress them up a bit.
The finished product turned out really cute, and our breakfast was a success!
