Our Good Samaritan craft for the little ones came from littleblots.com.  You have the option of printing the Band-aid boxes in color or black and white.  If I’d been thinking clearly, I would have printed ours on cardstock, but I was not, therefore I did not.  The kids just colored their “box,” folded it closed and we put a couple of small Band-aids inside.  You can tape the front flap to the back, on the sides.  That way you’re able to tuck in the top flap.  I hope that made sense.
