Infinity uses templates to determine various effects on models or defining particular areas of the table. Just like many table top wargames. There are a number of manufacturers out there that produce templates for Infinity, both official partners to Corvus Belli and not those not endorsed by CB. Here is a few retailers, in no particular order:
Corvus Belli themselves supplies templates to print free. You can print out templates and markers from the Downloads section of the Infinity website. Also if you bought one of the large starter sets such as Operation Icestorm you’ll have some card stock templates. While the US Ariadna Army Pack came with a card circular template and both sizes of teardrop templates. Card is perfectly fine, but it’s more useful to have a more durable set of templates. So I thought I would design my own set of templates and get them laser cut by Cog ‘O’ Two.
