Each year for my Open House, as well as parent-teacher conferences, I put up a small table, covered it with a seasonal tablecloth and set a basket of mints on it, along with a sign that said: "Families Are Worth A Mint! Help yourself."
While doing research on the web, I came across a variety of similar ideas, including this adorable poem that was pinned, with no link to who the original writer was. I decided to jazz this sweet sentiment up with a bit of clip art and my original saying. Simply print and mount on construction paper. I've also included some larger mints so you can reproduce my entire display. Enjoy! :-)
