Last year, the TMI household hosted 20+ for Thanksgiving. It was a blast! I started things off with a fun family project. In the foyer, I hung two large sheets of paper (Post-It makes large easel-size sheets that are like giant sticky notes) with the caption "Welcome, family and friends! Happy Thanksgiving!"
I then posed a question: "What are you thankful for? Share your blessings with us!"
I left a few markers on a table near the paper, and drew my own little hand-turkey with a message to get things started.
