Remove dough from cans; do not unroll. Break each roll of dough into 2 sections (there is a perforation in the middle of the roll that will allow you to separate the roll into 2 pieces). You should have 4 rolled sections of dough. Cut each section into 8 slices (16 slices from each can). Place slices, cut side down, on ungreased baking sheets to form trees. To form each tree, start by placing 1 slice for top, arrange 2 slices just below, with sides touching. Continue arranging row of 3 slices, then row of 4 slices, ending with a row of 5 slices. Use remaining slice for trunk. Refrigerate one tree.
