To harden cardboard for cosplay, start by cutting your cardboard into the desired shape. Then, mix equal parts of PVA glue (white school glue) and water to create a sealant. Apply this mixture to both sides of the cardboard with a brush, allowing it to dry completely between coats. For additional strength, consider adding layers of paper mache or plaster over the cardboard once the glue mixture is dry. Finish by sealing with a clear varnish to waterproof and protect your creation. This method ensures your cardboard remains lightweight yet becomes significantly more durable for cosplay use.
