One way my family likes to show what we are thankful for each year is by making Thankfulness Turkeys. We cut out a basic turkey shape in tan, and feathers in several colors. We then write out what we are thankful for on the featuers, and attach them to to the turkey bodies. This year I hung them on the door that you first see when you come in for the garage. It is a constant reminder of how much we have to be thankful for.
I was especially happy with how much Kara was thankful for. She had so many feathers that she was too tried to color them all.. =)
