What I have to ask is not part of the topic. But where can I find templates to download for free?
Just Google “scrivener templates” and you’ll get all sorts of sites.
In my experience, most Scrivener “templates” people send around the web are projects, not templates. Pay attention to the file extension.
But a project can be stripped and saved as a template, so if a project comes close to what you want and there are no alternatives, seems OK to me to grab the project, clean it out, then Save as Template.
