my collection so far.
I most often use the regular (BH or 2B) fillings in a mechanical pencil. With these I find it’s much easier to be precise than with conté or charcoal. Charcoal however is a great material for more rough sketches. It gives a way darker black compared to the greyish tint of most pencils, but being precise is a lot more difficult as the common sticks are too soft to create a sharp point for drawing.
more to come...
I hope I will find some extra time to add fresh sketches or drawings here some time soon : )
