I was welding Sogyo-no-Kotowari from Bleach when it got knocked over in the shonen-ai panel and it broke :/
Someone suggested to grab some duct tape (It was a soi-fon cosplayer xD) so I grabbed some from the boffering tournament table. Then an idea popped into my head that next year PortCon should have a little Cosplay repair booth with things like;
A sewing machine (I know friends who would donate them)
Extra crafting materials (Felt, thread, ribbon, etc.)
Duct tape/fast-drying glue
If it's negotiable, maybe charge a small fee for the items so it's beneficial towards next year's convention?
