Paper Kunai

Here I will show you how to make a paper Kunia.

First You need to print and cut the print out below. Now fold along the lines. At the line going horizontily on each side there should be to cuts. You might need to resize the print out below. At the cut tape it together. Do this for both of them. Now tape them both together.  

Now fold the rectangle together down the middle. Now roll it as tight as you can and tape it to the bottom of the other part.
