Edit: I made this. It is unofficial. It is not affiliated with Catalyst, or FASA, or anyone else for that matter...

It has an instruction file in the zip. It is compiled as PDFs for A4, but if you just scale it down to letter paper it will work the same... The cards will just be a little bit smaller...

I have SVGs of the pages as well if anyone would like them... I will also work on making a US-Letter sized template later this week.
