Answer 2

Roll your dough into a circle or a rectangle. Depending on if you want to make something like sweetrolls or not, place your filling in the center and fold the dough over it in a rolling motion. Continue rolling and place seam side down on your cutting board. You may then bake the whole thing, or cut it into slices, or make cuts in it and then create a "ring" by attaching the ends with more dough. Be sure to brush with melted butter or an egg wash and sprinkle sugar and cinnamon on top.
