How to use paper to fold the simplest dart

Next we will be the paper longitudinally divided into two, and then we take a piece of paper, it will be longitudinally folded evenly.

2, folded after we have no openings to the side, from the edge of the 90-degree angle down to the fold, this time we also have no openings to the side, again at a 90-degree angle down to the fold, pay attention to our folding time to leave a small slit, wait until we folded ninja darts last step to be used.

3, after folding we can see, folded out like an isosceles triangle, and then we have to turn this paper over, still no opening side to 90-degree angle folded, folding this corner still we have to leave a seam.

4, then turn the paper over again, this time we have an opening with a 90-degree angle folded, we cut off the excess paper, we will see two bottom edge to bottom edge of the two isosceles triangles. We will now use the paper that we just split in half, and use this paper in the same way to fold an isosceles triangle with the same base to base.

5, after getting good, we will be the two pieces of paper in the form of a cross, to overlap the two pieces of paper, overlap I will be each corner inserted into the seam, all inserted after our ninja shuriken is completed.
