I made a sign to promote our show. Isn't it a beaut?
The best thing about adopting the aesthetic of "things that were knocked up in a back yard" for your show is that anything you then knock up in your back yard for it is 100% on-brand.
Consider this a friendly, local pub. Make yourself at home, bring your friends, have a good time! Meet new people, have a laugh, enjoy the ambience, and the Oxford commas.
