the block is called Drunkards Path. there are many settings using this block and every setting has a different name. this setting in one of my favorite, it's called "Love Ring". i quilted a small one years ago as a wedding gift for a friend. i quilted dancing entwined hearts in the open areas, outline quilted the floral areas. in your quilt it would be white hearts, blue outline. beautiful quilt. did little sis say "SCORE!!"?
