An old idea worth revisiting:
Events always have a use for swag of all sizes – for organizers, for small prizes, to stuff gift bags to attendees. It would be great to have standard event-boxes (perhaps small, for a ~30-person event, and large, for a ~100-person one) that include a mix of broadly useful swag!
High priority: easy bulk gifts w/ icons that are easy to make by the 10k but hard to make in batches of 50 – stickers, buttons, pins, erasers, small toys, postcards, wikidice. Med priority: things that never go out of style and that we use a lot of, like sticky pads or sharpened throwing-barnstars or realistic stroopwafel-coasters. Lower priority: language-specific designs; reusable, collapsable event items like table- and floor-stand banners.
Event organizers may run a number of smaller events each year, and local communities often attend conferences thrown by others [and may have tables there], so when planning for volume, it may be good to ensure every group of whatever size has at least a small box on hand. Warmly, SJ
