In this step, you will burn the edges of the shirt. Dont burn all the way around though because the shirt will fall into 2 peices. Also, dont let the fire get to big because it is hard to stop. I had to run to the sink numerous times. I suggest staying near the sink. You can also take a match a just press it into the shirt and a hole will form. BE CAREFUL, THIS IS FIRE!!!
