What i think

For a tessellation you have to choose a variety of colors. You can choose one or two but it will sure look nicer if you choose more.  I chose 8 different colors; Blue, green, red, purple, yellow, baby blue, turquoise, orange. My tessellation was kind of like a hexagon I only did 3x4 on the front of my shirt. You can add more if you’d like to. Now you have done the tessellations on a paper put that paper inside the shirt and some newspaper under so that the colors won’t go to the other side. You are going to trace the tessellations onto the shirt. If you’d like to spread the colors I suggest to first plan how and where you are going to spread the color. And for that you first combine vinegar and alcohol and spray it onto the shirt. Then use a marker I used purple I just sprayed the alcohol then put the marker and just make my design. It really came out good. Well just hope this works well for you good luck. :)
