Hypothetical: 150 people are attending a workshop that you're hosting. Budget: $18 per person. The product has to do two things: 1. It must be used during the workshop. 2. It must have a legitimate reason to go home afterward. What would you make? No defaulting to the usual suspects (mug, pen, t-shirt, cap) just because they fit the budget. Tell me the product, how it gets used in the room, and why someone would still want it a month later.
