Here is a list of my current favorite free fonts that I use in my projects. As of when this was posted, these fonts are all free and can be used for commercial use! Links to download each font are below.
If you have any favorite free fonts, feel free to share them in the comments below! I'd love to hear what yours are! Also, these fonts are free - but I'm sure the authors would appreciate a donation if you have change to spare. Most of these links have a way to donate to the font creator if you'd like to.
