Right now, I have a separate plug-in drawing tablet with pen, but I'm not so good at it, because the spatial differences between the screen and tablet kinda confuse me. But! I have an HP computer with a touch screen, and I would love to be able to draw straight onto the screen. I've tried my fingers and those wide iPhone stylus, but those are to clunky for fine lines and drawings. And my tablet pen doesn't work on the touchscreen. Does anyone know what kind of stylus can be used with these computers? Or how to make one?
