Heat oven to 375°F. On cutting board sprinkled with 1 1/2 tablespoons of the sugar, separate dough into 4 rectangles; firmly press perforations to seal. Lightly press dough into sugar. Brush rectangles with about 1 tablespoon of the melted butter; sprinkle with remaining sugar. Using 2 rectangles, place one rectangle on top of the other. Starting with the shortest sides, roll up both ends jelly-roll fashion to meet in center. Cut into 8 slices. Repeat with remaining 2 rectangles, forming 16 slices in all. Place, cut side down, 2 inches apart on ungreased cookie sheets. Brush with remaining melted butter.
