I don't see a forum specifically related to education and workshops, so I hope this one is associated with that.
If this has not been addressed, I would like to propose a workshop -- ideally preceding a march/demonstration -- to put together effective signage.
The main issue I've seen: Legibility. It is simply not possible for human eyes to read many of the signs from a distance, and especially from a moving car. The type is too fine or too small, and there are too many words to read in the span of a few seconds.
Another issue: Message. I understand the decentralized anti-ideological model, and respect people's preference to make their signage however they like, so my suggestions would be voluntary. But I think it'd help dispel notions that this is a movement without a cause if a larger number of our signs were directed toward specific and consistent ends.
This ideal could be met by:
- providing optional prefab signage.
- brainstorming slogans and letting people write their own interpretations of them into their signs.
- offering a topic, letting people riff off of that during or after the brief signage workshop.
