R.I.Pen

My drawing pen just died...

Curves and straight lines come out jittery, no matter how much I tweak stability and clean the nub of it still jitters.

Granted I'm not that much an artist however, I liked drawing my friends and I like drawing my online persona on my own as I really can't pay artists to draw something I can only put into words and then get upset when I pay them for something not entirely drawn the way I want. Also for some reason I'm always picking a card that doesn't allow direct to person transfers and I think it's just a curse...?

Either way, no idea what to do- debating on just getting a drawing tablet or learning to draw with a mouse so any help is appreciated
