I'm considering starting to draw! I'm someone who is like, stick figure level currently so I'm literally starting from scratch ;P
My question is basically: When I have to write a lot with a pen or pencil my hand cramps up really badly due to me having developed a habit from childhood of holding it incorrectly. It's exactly like pic related.
If/when I start drawing, should I correct this from the very beginning or just I start off holding it like I do already and then kind of phase it into holding it correctly? If I forcibly correct it from the beginning it'll be way slower progress I think. Hope this makes sense and thanks in advance!
