how to make a pencil with a rubber shape

I'll give you a tutorial how to make a pencil drawings were rubbery. 

I use adobe illustrator cc2015 as software to make, the first step I would do is make the pencil shape by means of a separate, 

1. the top of the pencil 

2. middle, and 

3. the bottom pencil

After all the images that have been made, I will make in the form of a 'brush'. 

This is the last stage in the manufacture of the pencil, and after the brush is made, please use the brush into any shape you desire. 

please watch my video below to see the full tutorial.
