Among trading card game players this style of playmat has existed for years but MetaMats is fairly new, advertising they're the originators of the full colour cloth playmat. In the past companies like Spellground would make their mats by screenprinting onto the fabric but I'm sure these are being made with dye sublimation. Do you think I'm on the right track? My main problem seems to be finding a suitable material that is similar enough and can be used for sublimation transfers. The video contains close-ups of the material so you can get a good idea of what its supposed to be like.
