I am a big advocate for taking care of your hands and also taking breaks during art. It can take a huge toll on your health if you aren't careful enough. (I've already started developing carpal tunnel in my right hand). How often do you take breaks? I take a few breaks here and there. I should probably take more but I get so into the piece I'm doing that sometimes I even forget to eat.
I forget to take breaks usually, but I am trying to be a bit more conscious about it and take those 10 minutes breaks to do something else.
Because I procrastinate a lot with my art I'm inadvertently saving my hands and wrists. I've actually never thought of it like that before? I still need to procrastinate less.
