Roll dough into a rectangle, about 15′ x 10′. Spread 1/2 C melted butter over dough to within 1″ of edges. Then sprinkle 1/4 C sugar and cinnamon evenly over dough. Roll dough up tightly on long side. Press edges to seal and form into a 12″ long, evenly shaped roll. With a knife or thread of dental floss, cut roll into 1″ pieces. Place rolls into greased 13″ x 9″ baking pan. Cover and let rise in warm, draft-free place until double in size, about 30-45 minutes.
