Selecting the correct medium determines whether your sign survives a four-hour march or collapses at the first gust of wind. The table below evaluates the primary materials used during the recent nationwide demonstrations.
| Material | Estimated Cost | Weather Resistance | Practical Trade-Offs |
|---|---|---|---|
| Corrugated Plastic (Coroplast) | $6, $12 per sheet | Immune to water; highly wind resistant | Requires oil-based markers; slightly heavier to carry for long hours. |
| Recycled Cardboard | $0 (Repurposed boxes) | Fails quickly in rain without lamination | Environmentally sound and easy to source, but wilts under heavy downpours. |
| Foam Core Board | $4, $8 per board | Moderate; edges swell when soaked | Extremely rigid and lightweight, but snaps easily along wind gusts. |
| Heavy Tagboard / Poster Board | $1, $3 per sheet | Poor; curls in high humidity | Cheap and easy to carry, but flaps uncontrollably in moderate wind. |
