Step 3: Connect the pieces.
Lay the sheets of duct tape that you made in a row face down, left side sheet on the left, back sheet in the middle, and right side sheet on the right. connect the left and middle sheets first by lining them up together and laying many strips of duct tape across them for a seam. Hold it on your back and make sure it covers your whole left side of your upper body, and your back, all the way up to your shoulders. If it reaches all the way to the right side of your body, then its ok and move onto next step. If it does not reach then make it wider by making another smaller sheet and laying it over it. Connect these.
