I've been getting more interested in typography, to the point where I'd like to start experimenting with illustrating letterforms and general type design, but other than "just start drawing on paper" I'm not sure where to begin.

The first four pages of Google results for "illustrating letterforms" literally all point to a book called Drawing Type[1] (similar results for similar queries), but flipping through the preview on Amazon, the book looks to be more for inspiration than instruction.

How do I get started here? What are good introductory resources? What are the tools of the trade?

Thanks for reading :)
