I did not have all the same supplies as the class - I used what I had on hand:
Cardstock paper printed with positive words and colored with Mr. Scent markers and water. Hearts and words cut from the same positive word paper printed out on printer paper. I used very watered down black watercolor for the shading of the hearts and a black Sharpie marker to make the outlines.
I did not have any ribbon or a hole punch to add to the bookmarks at this time... I still think they turned out rather nice and they will be fun to send to my pen pals :)
