ELI5: Why only somethings work on touch screens, and others don't, fingers but not fabric?

This might have been answered in a ELI5 about touchscreens but I didn't really see an explanation about what works and what doesn't.

Most touchscreens work using something called capacitive sensing. Basically, the touchscreen uses a conductor to detect when something is nearby. The human body is also a conductor, and therefore it can interfere with the electrical field of the touchscreen. The screen uses this to detect how a human is interacting with it. Fabric does not conduct electricity, so it doesn't interfere with the electric field.
