It really bothered me that I did not read the challenge well, so I decided to make another one.
And this time completely with pencil.
I found out how to get the black as dark, and the stripes as thin as possible.
I used a B2 pencil, and kept it very sharp.
I sharpened it so often that my pencil is now half it's length.
But it's the only way to work with it as if it's a fineliner.
I hope you like it.
