This is an original, fun creation: the ninja star! Use it to throw for fun or to put in a collection. My difficulty: Easy-Medium. Length: Short-Medium.
You will need:
Step 1: Type of Paper
In this creation you will need two square 8.5 inch by 8.5 inch papers. In the next step there will be a link on how to turn A4 paper into a square. If you already have 8.5 inch square paper or know how to do it, then you can skip the link on the next step.
Step 2: Turning A4 Into 8.5 Inch by 8.5 Inch

Step 3: Fold in Half 3 Times
Take one of the two squares and fold it in half. Then fold it in half the same way. Finally, fold the paper in half the opposite way (if you did horizontal, do it vertical, vise versa).
Step 4: Folding Along the Crease
Unfold the last fold in half you made to create a crease. Then take the bottom left corner and bring it so the whole side of the paper meets up with the middle crease. Do this with the top right corner, too. Both corners must be facing the opposite way.
Step 5: The "Z" Fold
Since we must do this to both sides of the paper to create a Z-like shape, focus on the left side first. Take the left corner of the left side (how convenient) and fold it down in a triangle fold until it meets with the other side of the left side. Remember to keep the paper the same way unless I tell you otherwise or else it will get confusing. Then take the bottom right corner (on the right side) and do the same thing: fold it up until it meets with the other side of the right side. If you turn your paper it will look like a Z.
Step 6: Repeat With the Second Square
Set the "Z" off to the side. Take the second square you made and repeat steps 4-6.
Step 7: Putting the "Z"s Together
Take the first Z (it doesn't matter at this point which is first or second) and turn it vertically so it looks like a "Z". Take the other and turn it horizontally so one of the points is up and the other is down. Then place it on top of the first one.
Step 8: Creating the Star
Time to connect the points to create the ninja star. This will probably be the hardest step because it can get confusing here. Take a point on the vertical paper. To know this it is better to have 2 different colors. Repeat until both points on the vertical paper are tucked under a triangle on the opposite paper. For the horizontal paper, there should be two pockets on the vertical paper for the points on the horizontal to tuck into. I will try to make this as clear as possible.
Step 9: Add Tape and Glue (Optional)
This step is fully optional, but I would highly recommend it. Take an 1-inch piece of clear tape and put it on the middle where the points meet (vertical or horizontal). Then take another and put it the opposite direction the first one was to create a plus (or an X if you turn it). Flip the star over. Take glue, not a glue stick, and put some around the edges of the part that it can slip under. Remember to put something heavy on it to dry.
Step 10: Finish!
You have finished your ninja star! I hope this lesson was clear and if you successfully made it please hit the "I Made It!" button.

As usual, this link has a slightly different building style that is a little tougher to me, but that is your opinion. Happy throwing!
