This we did for YW beehive class act. and thought it was really cute for the girls to be excited to share this fun tradition with their families! I originally saw this idea over at
http://www.beckyhiggins.com/blog/labels/post-it%20love.html she even has the downloads if you didn't want to do your own labels.
I just tweaked mine a tad. Our family has enjoyed this new tradition...it's fun to see the little notes everywhere! I plan on doing this for my VT too...with the message inside....FuN!!
