Spoon the filling you've chosen to fill your braid down the center of the rectangle. Starting with the top and bottom “flaps”, fold the top flap down over the filling to cover. Next, fold the bottom “flap” up to cover filling. This helps keep the braid neat and helps to hold in the filling. Now begin folding the cut side strips of dough over the filling, alternating first left, then right, left, right, until finished. Trim any excess dough and tuck in the ends.
