Our Primary gave these boxes to the teachers, and I thought they were such a good idea for Valentines. You use a pattern and make the box out of cardstock. It fits 8 hersheys nuggets perfectly. You can use address labels to recover the nuggets.
I am going to make them for Robbie's classmates and let him decorate the top (maybe a starwars picture with a pop-up dot) Then Ill print the labels with either the child's name on it or with cute valentine sayings.
Let me know if you want to try it and I'll email you the pattern.
