We play a game called the Left Right story. Someone created a cute story where the family's last name is Right and the words left and right are constantly said in the story.
What you do is have everyone bring a fat quarter. Have them stand in a circle with their fat quarter in their hand. Have someone read the story and every time the word "left" is said, pass your fabric one person to the left, every time the word "right" is said, pass your fabric one person to the right. It's a lot of fun! There is Grandma Right, Sister Right, Mother Right, Father Right, etc. When the story is done, you keep whatever piece of fabric you have in your hand.
This works great with a group of about 15 people.
We also play Quilto. Of course, we use M&M's to cover the Quilto board. Somehow, I end up not being able having enough M&M's to use on my board :D
