Before you start, you have to know how big you want your armature to be. While I was playing around with it, the armatures are either too big or too small. Once you know the size, we can get start with it.
Tools we need:

One or two wire clipper, and a wire cutter. Not to mention the materials we need, aluminum wire, lots of it.
First, we start with two wires both with length of 25 inches long, take one wire, find the middle point, and then bend it, and twist it using the wire clipper (clip on one end and then start twisting) to make the head, turn it in to something like this:

This will give my armature around 12 inches tall.
Then, for the other wire, which is 25 inches long, we cut it at middle point, We will use it to make the arms. Then, we find the middle point of the armature I just built before. In this case, the middle point will be 6 inches from the head(or leg...). We apply the same concept, we take one of the shorter ones we just cut and start twist it together with the previous one, make sure that we are twisting the direction of the head instead of the feet... and we have:

Now we are almost done, all we have to do now is just twist the two leg wires together:

And this will give me an armature that is around 11 inches tall.
And here is the result:

Note: we can start with some longer wires and then cut it to the size we wanted after we done, but have to make sure that the ratio is correct: the leg is equal to half of the armature's entire height, meaning if the armature is 14 inches tall, then the legs has to be 7 inches long. And don't forget, when we extend the arms, it has to equal to the height of the entire armature!
And here is a small one, which is around 5 inches tall.

If there are any things unclear, please leave a comment, thanks!
