How do Granma,Granpa,and Little Tree appear on sundays? Chapter 15

Every Sunday, Little Tree and his grandparents go to church. They dress up in clean clothes and button up shirts. Granma always wears an orange, gold, blue and red dress that strikes her ankles, which Little Tree thinks makes her look like a spring flower floating down the trail. On the way to church, they always stop to visit Willow John, an eighty-year old full Cherokee, as tall as Granpa, with white plaited hair hanging below his shoulders and a flat brimmed hat.
