It's super easy. I typed out the messages on a 4x6 cell table on Word, cut them apart, punched a hole in the top and bottom of each Valentine, and stuck the straw through.
With the pencils, though, I had to make 3 notches in each hole to make it big enough to slide the pencil through. A larger hole punch would have been helpful. Oh, well. They still turned out cute, right?
I hope you all had a fantastic, romantic, sweet Valentine's Day!
