A quick and easy teacher/friend gift

I did these last year for the boy's teachers, principal, aides, specialists etc...seriously I made like 30.  I filled them with homemade caramel but you can fill with anything if you want it even easier!  Here's what I did-
Nathaniel wrote "You Rock" on a rock (duh) and then held it up for a photo.  I like using a short focal length so the rock is in focus but he isn't.  Then print them out on regular paper...the size depends on your bucket.  I made them 2x3ish inches.  Last, Mod Podge them on and let them dry!  Make sure you put the Mod Podge under and over for ultimate hold!
