My wrist hurts… tiny phone screen is easier to handle than a sketch book but = tiny repetitive movements of the wrist. And it’s hard to go tiny enough on details.
I’m considering saving up for an iPad or drawing tablet and pen but that’s a lot of money for something just to do art.
There's lots of options other than iPads. I have an s6 lite which works great. Check out Brad Colbow on YouTube for dinner go reviews. https://youtube.com/@thebradcolbow
