Jason Stahl was kind enough to share a couple of templates that he made for the Affinity suite of products, useful to those of us toiling away on TTRPG projects. I’ve linked to the forum post that contains his links. I will be adding my own hex-map template (once I essentially remake it since the current one is a MESS). If you have any resources to share, drop them here, drop them there, but drop them somewhere so we can spread the knowledge and help each other out!
I just found this mentioned on the throne of salt blog shouting out a design file from Clayton Notestine. https://www.explorersdesign.com/products/classic-explorer-starter-template
From the website - it’s inspired by a review of the ItO layout, but it also includes notes and tips rather than simply being a layout. There is a paid version as well.
