Preheat oven to 350°F. Spray a 11x8.5 inch casserole dish with non-stick spray.
In a small bowl, combine cinnamon and sugar, set aside.
In a large bowl combine the flour and salt.
Cut the shortening into the flour mixture until crumbly and it resembles wet sand.
Stir in the water and form a dough.
Dump the dough onto a floured surface.
Separate the dough into 2 even portions.
Roll each dough ball, one at a time into a rectangle. The dough should be thin. Try to get it to be 13 x 9 inches or larger. It should be about 1/8 inch thick.
Spread 1/2 cup of softened butter over rectangle then sprinkle cinnamon sugar evenly over butter.
Roll jelly-roll style into a log.
Pinch ends closed and place in prepared pan seam side down. Repeat process with the second ball of dough.
Place the second 'log' in the same casserole dish. Decorate the top with dough scraps if desired.
Bake at 350°F for 40 to 45 minutes or until the top of the roll is golden.
