So glad you are loving the course!
As far as I can tell there really isn’t a way to edit the names of fonts. I would just make a list of which fonts you can use for commercial use on your computer or in a notebook. It would be nice if Silhouette would allow you to make different folders or lists of fonts, but I don’t know of any way to do this.
*If anyone in the group knows how to do this, please let us know!
Sizing will just depend on which planner you are using. A lot of the planners I make stickers for have the 1.5 width, so I just make sure that my scripts are 1.5 or lower. Hope this helps!
