I had a 20-person brainstorm meeting planned- in a room without whiteboards. Usually a nightmare! I put a couple of the giant post-its in each corner, and had people break out into groups to discuss and document their ideas on the post-its. It was great because when we came back into the large group, everyone could see each team's ideas, and commit to making an idea happen. The meeting was really productive, and having these really made the difference. (I did receive a free sample from 3M in exchange for a review, but I already loved the product!)
