A tutorial! I found a tutorial to make I Spy bags at "Craftiness is Not Optional" . I have made two so far and they are very easy to make. I would suggest looking at places like Oriental Trading Company for the little goodies to put in the bags. I used left over toys from around the house and a few things I found at Hobby Lobby and Big Lots.
