I recorded a video where I show some basics on how to create icons in Figma, or at least how I do it.

This video goes through some basic techniques including

1. Working with keyshapes
2. Useful shortcuts
3. Pixel grid/align to pixel grid settings
4. Basics of the pen tool
5. Rounding of start and end points
6. Rounding of joins

If you think this is interesting, leave a comment or a like to the video, so I know to make more videos like this.
