Howdy.

I have been watching DiscipleDrew's videos a lot lately (SCORE!) and he had a vid about the Nationals tournament last year. There were pictures of playmats with a basic layout of cards, one with the artwork from the "Gates of Hell" card from TeXP (which looks Mordor-y and awesome) one which looks a lot like the Redemption CA play area style. Where did these come from? If these were custom, how did you make 'em?

Cool! I was actually considering making my own and see how the look. (Though the won't look as awesome as the "Gates of Hell" one did though.)
