B2 Pencil Drawing. It is too hard for drawing but it can be used for technical drawings. However the full range on pencils is H9 H8 H7 H6 H5 H4 H3 H2 H HB B B2 B3 B4 B5 B6 B7 B8.
So a B6 is softer and darker than a B2. It then moves into HB and then B1 B2 etc towards B9. So a 2H Pencil is harder than a 1H graphite Pencil and a B2 Pencil is softer than a B1 Pencil.
Pencil near lava or a fire.
I enjoyed the process. When using harddark pencil like B2 it is important not over shade. I have never tried intuitive drawing before but after reading your personal story I though I ought to give it a try. I enjoyed the process.
