Step 8: Layer 4
Begin as you did with layer 3. Cut 6 11.25in strips of tape. Place sticky side down on top of layer 3.
Cut 7 more 11.25in pieces. Place sticky side down directly above the 7 non-covered 11.25in strips of layer 3.
After placing all 11.25in pieces of tape, cut 5 19in strips of tape and place as you did with the previous strips.
