I saw this on a blog somewhere recently (I have no idea where!), and thought it was a great idea :) I painted O's foot white and then pressed it onto the black construction paper. Once the ghost dried, we glued the googly eyes to the heel, and I wrote the message with a silver sharpie. I had O sign her name. I planned on her writing an O, but she insisted on writing and M (her version) for Mommy. Her M's are basically just a few lines. I said "Oh, it's an M," and O said "No, it's not. That's just lines! O not know how make M!"
