I made this for a friend of mine, who reached this milestone waaaaaaay before me! I covered the wooden frame (Michael's) with designer paper (also from Michael's). I then spelled out my sentiment with pebbles (also from you know where), glued them in place with Tacky Glue and covered the entire project with Mod Podge. I printed the poem that I wrote on the computer and then inserted it in the frame. My dear sweet friend loved it! Hope you do too! PS - there really are literally 60 rocks! Count them yourself and see!
