Simple, easy, time consuming paper armor. Just need duct tape and plain paper.
Step 1: Rolling
Take a piece of paper by the corner and roll it as tightly as possible towards the opposite corner. Once rolled, tape it in place.
Once it is rolled it should be about 13 inches long and have about a 1/4 inch diameter.
For full arm guards you will need about 20 rolls for each of your upper arms and 15 for each of your forearms. This will change depending on how wide your arms are.
Step 2: Taping
Once you have enough rolls, you must tape them together. Line up your rolls so that the ends meet on one side but fan out near the top. Tape them together about 1 inch from the bottom. Tape again about 3 inches from the top.
Step 3: Fashoning a Strap
Take a long piece of duct tape (circumference of your body part times 2 + about 6 inches) and fold it almost in half so that the sticky sides meet and only about 3 inches are left sticky. Weave the side with the folded edge through about 5 rolls (over, under, over) and tape it in place. Then put it around your arm and tape the other side of the strap so it fits snugly.
Step 4: Done
Thats it, this works for most of your appendages and it really does make blows hurt less, but after a while it starts to sting. They take a while to make and restrict movement some but there isn't much else for me to do in school so these happened. These can go on arms or legs and i may make a full body suit if there is any response to this. Goodbye.
